FACT-CHECK: Moscow Convicts Ukrainian Soldiers for "Terrorism" — The Geneva Convention Says No

Introduction: Prisoners of War in the Dock as Terrorists

An unprecedented wave of convictions since the Kursk fighting

Since the Ukrainian incursion into Kursk Oblast launched in August 2024, Russia has systematically paraded captured Ukrainian soldiers before its military tribunals — not as prisoners of war, which they are under international law, but as terrorists. The number is staggering: according to analysis published in 2025 by the Kirill Parubets Analytical Center and the journal The Insider, relayed by the Kyiv Independent, 305 Ukrainian soldiers had already been convicted on terrorism-related charges, including 290 who are recognized prisoners of war. More than 50% of the 525 Ukrainian POWs whose capture in Kursk Oblast is publicly documented had already been convicted.

In the week of June 13–20, 2026, the Russian judicial machine showed no signs of slowing. On June 19, a court sentenced Vladimir Semylouta, a soldier of the 95th Air Assault Brigade of the Ukrainian Armed Forces, to 15 years in prison, including 4 years under a strict prison regime — for allegedly crossing the border in March 2025 and participating in an "armed blockade" of the village of Olishnya in the Sudzhansky district. The terms used by the Russian Investigative Committee: "act of terrorism" under Article 205, clauses "a" and "v" of the Criminal Code of the Russian Federation. What Russia omits to mention: this man was a combatant in uniform, captured in battle, protected by the Third Geneva Convention.

This fact-check has a clear purpose

The purpose of this article is not to defend every act of every soldier on every front. The purpose is to verify a precise legal claim: is it lawful, under international humanitarian law, to prosecute a prisoner of war for "terrorism" on the grounds that he participated in combat within the framework of an international armed conflict? The answer provided by the texts, legal experts, and international organizations is unequivocal.

What I will demonstrate here, with figures to back it up, is not an activist reading of the law. It is the reading of the International Committee of the Red Cross, of Human Rights Watch, of the ISW, of Euromaidan Press, and of several specialized jurists. Russia is not reinterpreting international law: it is deliberately trampling it.

What the Third Geneva Convention Says: Prisoner of War Status

Who is a prisoner of war under Article 4?

Article 4 of the Third Geneva Convention (August 12, 1949) defines prisoners of war as persons belonging to the armed forces of a party to the conflict who have fallen into the power of the enemy. Members of regular armed forces are explicitly cited as the first protected category. A soldier of the 95th Air Assault Brigade of the Ukrainian Armed Forces — a regular unit, in uniform, captured during combat — meets all of these conditions without ambiguity. Doubt cannot apply here: Article 4 specifies that in cases of doubt, the person is presumed to be a prisoner of war until a determination is made by a competent tribunal.

By labeling these soldiers "terrorists" and prosecuting them under ordinary Russian criminal law, Russia retroactively denies their status as lawful combatants. This is a deliberate legal maneuver aimed at stripping them of the protections conferred by international humanitarian law — while branding them with the heaviest criminal stigma in the Russian code. Article 4 of the Third Geneva Convention renders this maneuver illegal.

Article 87: Sentences cannot exceed what the law prescribes for the detaining power's own soldiers

Even when a POW has committed an act that is actually prohibited, Article 87 of the Third Geneva Convention sets strict limits on sentences: no sentence may exceed that applicable to members of the armed forces of the detaining power for the same acts. The tribunal must take into account the fact that the accused is not a national of the detaining power, owes it no allegiance, and finds himself in its power independently of his own will. Collective punishments, corporal punishment, and any form of torture or cruelty are expressly prohibited. Yet the documented sentences range from 13 to 28 years in prison, with some receiving life imprisonment. Could one imagine a Russian soldier being sentenced to 20 years for crossing a border during wartime?

Article 87 adds a crucial specification: the tribunal may reduce the prescribed sentence and is not bound to apply the legal minimum. In the trials brought against Ukrainian POWs, none of these protections is respected. The hearings are expeditious, defense lawyers are court-appointed, and the accused are denied communication with their families or with the ICRC.

Article 99: A POW May Only Be Tried for Acts Prohibited at the Time They Were Committed

The fundamental principle of non-retroactivity applied to POWs

Article 99 of the Third Geneva Convention establishes an absolute principle: "A prisoner of war may not be tried or sentenced for an act which is not forbidden by the law of the detaining power or by international law in force at the time the act was committed." It also prohibits any physical or moral coercion to obtain confessions, and guarantees the accused the right to present a defense with the assistance of a qualified lawyer. In the documented Russian trials, these guarantees are systematically violated. Defendants report interrogations under duress and limited access to their legal representatives.

Euromaidan Press documented on June 17, 2026, the emblematic case of Dmytro Lebedev (29 years old) and Vasyl Mukhin (45 years old), two POWs from the Azov Regiment sentenced to 17 and 20 years respectively in a strict-regime penal colony by the Rostov-on-Don military tribunal. The charges: participation in a "terrorist organization" and "training for terrorist purposes." The crucial legal point: Mukhin had joined Azov in 2015 and had been captured during the defense of Mariupol in May 2022. Russia's Supreme Court designated Azov as a terrorist organization on August 2, 2022 — that is, three months after his capture. Convicting someone for membership in an organization designated as terrorist after his capture is a manifest violation of the non-retroactivity principle enshrined in Article 99.

The admission of the absurd: soldiers convicted for fighting a war

Sergei Davidis, director of the Political Prisoner Support Project (Memorial), framed the problem with devastating legal precision. According to him, "a comprehensive analysis of international treaty norms suggests that terrorism charges are, in principle, inapplicable in a situation of international armed conflict." He added: "The specific acts described in these sentences are either not crimes, or violations of the laws and customs of war, which must be proven and prosecuted. Since no such charges are actually brought, the prosecution proves to be conducted for the mere fact of participation in military actions, which genuinely contradicts the Geneva Convention on Prisoners of War." These statements were reported by the Kyiv Independent. For making them publicly, Davidis himself was sentenced in August 2025 to six years in prison in Russia.

Defendants in the mass trial of March 2025 declared to the tribunal, according to Euromaidan Press, that the charges required no proof beyond the four letters of the Azov regiment's name. This is not justice. It is a criminal nomenclature disguised as procedure. And the Rostov-on-Don tribunal has become, over the course of 2025 and 2026, a sentencing assembly line — dozens of convictions handed down in batches, from 13 to 23 years, with no notable individual variation.

The Kursk Case: 525 POWs, 305 Convictions, a Figure That Runs Cold

The numbers behind the wave

The Ukrainian incursion into Kursk Oblast, launched in August 2024, led to the capture of an unprecedented number of Ukrainian soldiers by Russia — 525 Ukrainian POWs whose capture is publicly documented, according to the Kirill Parubets Analytical Center and The Insider. Of this number, 305 had already been convicted at the time of the analysis's publication, including 290 recognized prisoners of war. Fifteen convictions were handed down in absentia. 228 POWs had not yet been convicted, but four were already under criminal investigation. These figures represent more than 50% of Ukrainian POWs captured at Kursk convicted in under a year.

The jurisdiction used: the 2nd Western Military District Court of the Russian Federation. Sentences handed down: 13 to 28 years for the vast majority. Only one POW was sentenced to life imprisonment. The criminal qualification: "act of terrorism" under Article 205 of the Russian Criminal Code. Yet, as the legal analysis makes clear, these Ukrainian soldiers did not plant bombs in markets or shoot civilians in an airport. They crossed an international border as part of a military operation by a sovereign state at war. That is the very definition of armed hostilities to which international humanitarian law applies.

The Semylouta case: 15 years for "blockading" a village in wartime

The case of Vladimir Semylouta, sentenced on June 19, 2026 to 15 years in prison, illustrates perfectly the mechanics of these convictions. According to the Russian Investigative Committee, Semylouta crossed the Russian border on March 14, 2025, entered the village of Olishnya in the Sudzhansky district, and allegedly, with others, "blockaded the locality", surveilling local residents and Russian military personnel. He carried an AK-74 Kalashnikov and grenades. These are standard military equipment for a soldier on operations. He was captured on April 9, 2025 during combat operations. The Kyiv Independent notes that the editorial team was unable to verify the claims of Russian authorities. The charges: Article 205, clauses "a" and "v" of the Russian Criminal Code. The legal reality: a soldier in uniform, openly carrying weapons, captured in combat, is a prisoner of war. Not a terrorist.

The Russian Investigative Committee systematically designates him with the term "боевик" — "armed combatant" — in a deliberately pejorative sense, never as "военнослужащий" (serviceman), never as a prisoner of war. This lexical choice is not incidental: it aims to strip the accused's legal status of its humanity before the tribunal even opens its mouth. Language as an instrument of legal war-washing.

What the ISW Says: Systematic Prosecutions in Violation of Humanitarian Law

A pattern documented since 2022, amplified in 2025–2026

The Institute for the Study of War (ISW), in its Russian Occupation Update of June 4, 2026, documented the case of Valery Osochenko, a soldier of Ukraine's 157th Separate Mechanized Brigade, reported missing during combat in Donetsk Oblast in August 2025. The Luhansk occupation prosecutor's office approved an indictment against him for "participation in a terrorist organization" — on the grounds that he had allegedly belonged to the Aidar Battalion. The ISW notes that Russia unilaterally designated the Aidar Battalion a terrorist organization in 2023, and that occupation authorities had, in all likelihood, fabricated the details of Osochenko's file to apply this charge. Osochenko, as a lawful Ukrainian combatant, should not be subject to any criminal prosecution under international law. The ISW concludes that his case constitutes a violation of the Third Geneva Convention.

The pattern is consistent: Russia unilaterally designates Ukrainian military units as "terrorists" — Azov in 2022, Aidar in 2023 — then uses these designations as the legal basis for prosecuting captured members under ordinary Russian criminal law, short-circuiting the protections of the Geneva Conventions. ISW occupation updates have documented this phenomenon continuously since at least late 2024. This is not an ambiguous legal interpretation — it is a structural, deliberate, and systematic violation of international humanitarian law.

The "assembly-line trials" and the logic of mass processing

The Rostov-on-Don military tribunal is the central jurisdiction for prosecutions of Ukrainian POWs from the Azov Regiment. Euromaidan Press describes it as a sentencing assembly line: multiple batches of convictions throughout 2025 and 2026 — three POWs convicted in March 2026 (5.5 years, 18 years, and 19 years), two sentenced to 18 years each in April 2026, then Lebedev and Mukhin in June 2026. The pattern is identical: designation of Azov as a terrorist organization, charges for "participation" and "training", heavy sentences under strict regime. One POW, Oleksandr Ishchenko, died in the Rostov-on-Don pre-trial detention center from a "closed chest trauma" according to Russian authorities — a formulation whose opacity escapes no one.

The European Union, in its conclusions of June 18, 2026 at the 11th EU-Ukraine Human Rights Dialogue, "strongly condemned Russia's war of aggression against Ukraine and its flagrant violations of international humanitarian law and international human rights law, including arbitrary deprivation of life and liberty, enforced disappearances, systematic torture and ill-treatment of civilians and prisoners of war." Those words are diplomatic. What they cover is far less so.

What Does the ICRC Say? International Humanitarian Law Versus Russian Practice

The procedural guarantees of Convention III

Article 99 of the Third Geneva Convention is explicit about procedural guarantees: no physical or moral coercion to obtain confessions, the right to present a defense, assistance from a qualified lawyer. Yet the report of the UK Senior Military Advisor to the OSCE Council, published on May 21, 2026, cites damning data: 96% of the 725 released Ukrainian POWs interviewed provided testimony of torture or mistreatment during their captivity in Russia. The Independent International Commission of Inquiry on Ukraine concluded in March 2025 that Russian authorities had committed acts of torture constituting crimes against humanity. In this context, the procedural guarantees of Article 99 are a dead letter.

The ICRC's database on customary international humanitarian law specifies that in an international armed conflict, every captured combatant must be recognized prisoner of war status. In cases of doubt, a competent tribunal — not the tribunal of the detaining power, but an impartial tribunal — must decide. Russia has put no such mechanism in place. It presumes status itself, decides guilt itself, and hands down sentence itself. A state acting as judge and party for its own prisoners of war — this is precisely the configuration that Geneva law is designed to prevent.

ICRC access: a major blocking point

On June 7, 2026, the Kyiv Independent reported that Ukraine had proposed during bilateral talks to allow ICRC representatives access to Ukrainian prisoners held in Russia. Ukrainian Ombudsman Dmytro Lubinets stated he had received "preliminary assurances" from the Russian side regarding monitoring visits to penitentiary facilities. As of June 20, 2026, these assurances remained unconcretized. Without ICRC access, Ukrainian prisoners of war are in a total blind spot of international law: no possibility of verifying their conditions of detention, attesting their POW status, or monitoring the regularity of their trials.

Ukraine has imposed sanctions on 29 individuals and 17 legal entities, including judges involved in the criminal prosecution of Ukrainians in Russia and temporarily occupied territories, as reported by Crimea Platform on June 17, 2026. This is a symbolically strong response — but it does not free the convicted. And without ICRC access, these trials will continue to operate in darkness.

The "Terrorist" Designation of Military Units: An Illegal Legal Weapon

The Azov designation: manifest retroactivity and violation of Article 99

On August 2, 2022, Russia's Supreme Court designated the Azov Regiment a "terrorist organization." Vasyl Mukhin had joined Azov in 2015 and had been captured during the defense of Mariupol in May 2022 — that is, three months before this designation. Convicting him of "participation in a terrorist organization" based on an act committed before the designation constitutes a direct violation of the principle of non-retroactivity in criminal law, enshrined in Article 99 of the Third Geneva Convention. This principle — nullum crimen sine lege, no crime without a pre-existing law — is one of the foundations of criminal law in any state governed by the rule of law. Russia ignores it deliberately.

The same mechanism applies to the Aidar Battalion, designated "terrorist" in 2023 and then used as the legal basis for charges against POWs captured before this designation. And the same mechanism applies to those convicted over Kursk: soldiers who took up arms as part of a lawful military operation by the Ukrainian state, prosecuted under Article 205 of the Russian Criminal Code — a provision designed for bomb attacks and hostage-taking, not for interstate military operations. Applying Article 205 to armed combat between states is to reclassify war as terrorism by decree — a semantic manipulation with no basis in international humanitarian law.

Why Moscow does this: the strategic objective behind the legal perversion

The approach is not accidental. By labeling Ukrainian soldiers as terrorists, Russia pursues several simultaneous objectives: justifying the refusal to include them in prisoner exchanges (a convicted "terrorist" cannot be "released" under a POW exchange without losing face), anchoring in Russian public opinion the idea that Ukraine is waging an illegitimate war, and making any future amnesty or peace agreement including the release of these detainees more difficult. This is a political weapon disguised as judicial procedure. And Sergei Davidis paid for saying so publicly with six years in prison.

Activist and jurist Mykhailo Savva, in his analysis published on June 16, 2026 via Inter Press Service, describes the Russian system as a five-step "chain of persecution" — identification, arrest, cruel treatment, sham trial, imprisonment — applied equally to civilians and military personnel. He concludes that each of these steps violates human rights and international standards, and that together they form "a unique, integrated, and deliberate structure." The normalization of these practices, he warns, does not concern Ukraine alone: it threatens the coherence of international law as a whole.

The European Union and the International Community in the Face of Convictions

Institutional responses: firm condemnations, limited effect

On June 18, 2026, the European Union and Ukraine held their 11th Human Rights Dialogue. The official communiqué condemns "flagrant violations of international humanitarian law and international human rights law, including arbitrary deprivation of life and liberty, enforced disappearances, systematic torture and ill-treatment of civilians and prisoners of war." These formulations are precise and use the right words. But they have, to date, produced the release of not one POW convicted of "terrorism." Sanctions against Russian-Ukrainian judges are symbolically important — structurally insufficient.

The International Bar Association (IBA), on June 15, 2026, condemned "Russia's intensified attacks against Ukraine, including the deliberate and repeated targeting of civilians and civilian objects", adding: "The IBA calls upon the Russian Federation to immediately cease all unlawful attacks and to fully comply with its obligations under the Geneva Conventions." IBA President Claudio Visco signed this statement. The legal message is clear. The enforcement capacity remains, regrettably, absent.

The Special Tribunal for Ukraine: a glimmer, but not yet a light

In June 2026, the states parties to the future Special Tribunal for Ukraine were meeting to establish the tribunal's governance body, elect judges, and designate a prosecutor. This tribunal — targeting the crime of aggression — does not yet include an explicit mandate for the mass violations of POW rights. The first indictments are expected once judges are elected and a prosecutor named. This is a step — but those sleeping tonight in Russian penal colonies after being convicted of "terrorism" for acts of war will likely not see their cases before this tribunal any time soon.

The Independent International Commission of Inquiry on Ukraine, mandated by the UN Human Rights Council, remains one of the most operationally active documentation mechanisms. Its findings have established violations of international humanitarian law, crimes against humanity, and have documented executions of captured or surrendering Ukrainian soldiers. Each report feeds the international criminal file. The question remains the delay between documentation and accountability.

Torture in Detention: An Additional Violation Compounding Illegal Convictions

96% testimony of torture: a figure that must be repeated

The statement by the UK Senior Military Advisor to the OSCE Council, Colonel Joby Rimmer, made public on May 21, 2026, cited data from international organizations: 696 (96%) of the 725 released Ukrainian POWs interviewed had provided testimony of torture or mistreatment during their Russian captivity. The UN Human Rights Monitoring Mission had documented, in February 2025, 79 executions of captured Ukrainian personnel during 24 incidents since August 2024. The OSCE Moscow Mechanism report of September 2025 reached the same conclusions: a systematic and widespread pattern, not an incidental one.

On June 17, 2026, UA.News reported that the SBU had gathered evidence against an agent of Penal Colony No. 4 of the Federal Penitentiary Service of the Russian Federation in the so-called "LPR", suspected of participating in the mass torture of Ukrainian prisoners of war between 2022 and 2026. During the prisoner "reception" procedure, Ukrainian soldiers were systematically beaten with rubber batons on various parts of their bodies and on their heads. The SBU explicitly notes that these acts constitute "a flagrant violation of the Geneva Convention relative to the Treatment of Prisoners of War of August 12, 1949, which prohibits cruel treatment or any action endangering the life and health of prisoners of war."

A death in pre-trial detention and the silence of Russian authorities

Ukrainian POW Oleksandr Ishchenko, a member of the Azov Regiment, died in the Rostov-on-Don pre-trial detention center. Official Russian cause: "closed chest trauma." No independent investigation was possible; no consular or ICRC access was guaranteed. Euromaidan Press documented this death on June 17, 2026. In a context where 96% of released POWs testify to torture, a formulation as vague as "closed chest trauma" to explain the death of an unconvicted prisoner, captured in combat, cannot be accepted without the deepest suspicion.

The combination of both dimensions — illegal criminal convictions for participation in military combat on the one hand, and systematic torture in detention on the other — makes the conditions of captivity of Ukrainian POWs in Russia a composite violation of international humanitarian law. This is not a legal grey zone. It is a documented double crime.

Prisoner Exchanges in This Context: A Deliberate Legal Complication

The trap of those convicted of "terrorism" in exchange negotiations

On June 5, 2026, the 75th prisoner exchange between Ukraine and Russia had brought back 185 Ukrainian military personnel and one civilian. On June 6, Ukrainian Ombudsman Dmytro Lubinets announced that both parties would "start from scratch" to verify POW and civilian hostage lists. These exchanges are vital — but they face a structural obstacle: Russia has convicted several hundred POWs for "terrorism", a designation that makes their inclusion in standard exchanges legally more complex. On the Russian side, releasing a "convicted terrorist" within the framework of a POW exchange is presented as an excessive concession. This is a calculated obstacle.

Militarnyi.com reported on June 14, 2026, that Russia was refusing to include foreign fighters captured by Ukraine in exchange lists — effectively excluding them from any agreement. Ukraine, for its part, seeks to comply with international humanitarian law in the treatment of its own prisoners. The contrast with Russia's treatment of Ukrainian POWs is documented and stark. The asymmetric conditionality of exchanges — Ukraine respects the law, Russia uses it as a pressure tool — lies at the heart of prisoner negotiation dynamics.

The repatriation of bodies: 522 on June 18, 2026

On June 18, 2026, Ukrainian authorities announced they had received the remains of 522 Ukrainian citizens, including soldiers, as part of the process of repatriating mortal remains. The Coordination Headquarters for the Treatment of Prisoners of War specified that forensic investigations and identification procedures would be conducted — without specifying the civilian/military breakdown among the 522. These repatriations of remains are painful but precious: they allow families to find closure and, often, provide documentation of circumstances of death. In some cases, the bodies bear marks of violence that feed the files before the International Criminal Court.

The question of repatriated remains carries an additional dimension: several Ukrainian POWs who died in Russian detention — such as Ishchenko — are not part of these formal remains exchanges. Their families do not know where they are buried. This dimension of the war — the war of bodies, of graves, of memory — is an additional suffering deliberately inflicted, in violation of Article 120 of the Third Geneva Convention on the treatment of the dead in captivity.

The Fact-Check: Summary of Verdicts on Each Verifiable Claim

TRUE: The convicted soldiers were lawful combatants in uniform

The convicted Ukrainian soldiers belong to the regular armed forces of Ukraine — 95th Air Assault Brigade (Semylouta), 22nd Separate Mechanized Brigade (Hrynchyshyn), Azov Regiment/12th Special Purpose Brigade (Lebedev, Mukhin). These are constituted units of the armed forces of a sovereign state. Under Article 4-A(1) of the Third Geneva Convention, their members who fell into enemy hands during an international armed conflict are entitled to prisoner of war status. This status is not subject to the discretionary judgment of the detaining power. This point is CONFIRMED and cannot be contested.

TRUE: The sentences imposed (13 to 28 years, even life imprisonment) are disproportionate and illegal. Article 87 requires that sentences not exceed those applicable to Russian soldiers themselves for the same acts. Would a Russian soldier who participated in military operations against Ukraine be sentenced to 20 years in prison in Russia? The answer is no. The disproportion is manifest and documented. CONFIRMED.

TRUE: The "terrorist" designation is legally inapplicable to acts of war

TRUE, according to Sergei Davidis (head of Memorial's Political Prisoner Support Project), according to Euromaidan Press in its June 17, 2026 article citing Article 99 of Convention III, and according to the ISW in its multiple occupation updates. The terrorism charge under ordinary criminal law is "in principle inapplicable in a situation of international armed conflict" (Davidis). Article 99 prohibits prosecuting a POW for acts not prohibited at the time of their commission — and participation in military hostilities by a lawful combatant is not a prohibited act. CONFIRMED.

NUANCED: certain individuals could theoretically be subject to prosecution for specific violations of the laws of war (documented executions of civilians, deliberate destruction of protected property, etc.). But none of the cases examined in this article rest on such acts: they uniformly concern the act of participation in combat itself. And for these acts, international humanitarian law is categorical: combatant immunity protects lawful POWs. The documented trials do not prove specific such acts — Russia has not proven them. IMPORTANT NUANCE.

What Putin Risks Before International Institutions

The ICC, the Special Tribunal, and the accumulating file

The International Criminal Court has already issued arrest warrants against Vladimir Putin and Maria Lvova-Belova for the deportation of Ukrainian children — a documented war crime. The file of POWs tried for "terrorism" feeds the international criminal case in several ways: the convictions themselves constitute evidence of systematic violations of humanitarian law, the documented conditions of detention (96% testimony of torture) reinforce charges of crimes against humanity, and the deaths in detention (Ishchenko) add to the 79 POW executions documented by the UN since August 2024.

The Ukrainian Prosecutor General's Office submitted to the ICC in May 2026 elements on the deportation of approximately 1,800 civilian prisoners from the Kherson and Mykolaiv regions to the Russian Federation, characterized as war crimes and crimes against humanity. These submissions create a growing documentary corpus. The question is no longer whether the evidence exists — it does. The question is whether the institutional mechanisms will be operational early enough to produce real accountability.

The Special Tribunal for the crime of aggression: a mandate to expand

The Special Tribunal for Ukraine, whose states parties were meeting in June 2026 to establish its governance structure, is focused on the crime of aggression — the decision to launch the war. Its mandate does not explicitly include the management of POWs. But crimes against POWs — torture, illegal convictions, executions of surrendering soldiers — fall under classical laws of war and could be brought before the existing ICC or before national courts through the principle of universal jurisdiction. Several EU member states have already opened national criminal proceedings against identified Russian military personnel and officials.

Ukraine is imposing sanctions on the judges involved in these convictions — 29 individuals and 17 legal entities targeted as of June 17, 2026. This is a symbolic pressure tool. The concrete effect on those convicted and held in penal colonies is nonexistent in the short term. The road to accountability is long. Which does not make it any less necessary.

Final Verification: What Is Confirmed, What Remains Uncertain

Table of verified claims

CONFIRMED: 305 Ukrainian soldiers convicted of terrorism in connection with the Kursk incursion — including 290 recognized POWs (source: Kirill Parubets Center / The Insider, reported by Kyiv Independent, 2025 data). CONFIRMED: Vladimir Semylouta, 95th Air Assault Brigade, sentenced on June 19, 2026 to 15 years (source: Russian Investigative Committee via mk.ru / vesti.ru, Kyiv Independent Kursk tag). CONFIRMED: Dmytro Lebedev (17 years) and Vasyl Mukhin (20 years), sentenced on June 17, 2026 (source: Euromaidan Press, 06/17/2026). CONFIRMED: Andrii Hrynchyshyn, 22nd Separate Mechanized Brigade, sentenced to 15 years (source: Kyiv Independent, April 2026). CONFIRMED: Article 99 of the Third Geneva Convention prohibits prosecuting a POW for acts lawful at the time of their commission (source: ICRC database). CONFIRMED: Retroactive designation of Azov as terrorist after Mukhin's capture (August 2, 2022 vs. May 2022 — source: Euromaidan Press).

UNVERIFIABLE FROM THESE SOURCES: Russia's specific claims about the precise "terrorist acts" attributed to each convicted individual — the Kyiv Independent explicitly states it could not verify Russian authorities' allegations. UNCERTAIN: the exact number of Ukrainian POWs still in pre-trial detention as of June 20, 2026 (2025 figures may have evolved). CONFIRMED: 96% testimony of torture among 725 released POWs interviewed (source: OSCE statement by British Colonel Joby Rimmer, 05/21/2026).

What this fact-check does not cover

This fact-check concerns the legal legitimacy of "terrorism" prosecutions against POWs in the context of an international armed conflict. It does not cover potential war crimes that individual Ukrainian soldiers may have committed — such acts would be handled under other provisions of humanitarian law (trial under Article 99 of Convention III for acts actually prohibited, with all procedural guarantees). It also does not constitute an exhaustive analysis of the situation across all fronts or of all Ukrainian POWs held in Russia. The data cited comes from verified sources published between June 13 and June 20, 2026, supplemented by the ICRC database on international humanitarian law.

The conclusion of this fact-check is clear: the "terrorism" designation applied to Ukrainian soldiers in uniform captured during combat in an international armed conflict is legally unfounded, contrary to the Geneva Conventions to which Russia is a party, and documented as systematic and deliberate. This is not an opinion. It is the verdict of international law texts and the legal experts who interpret them.

Conclusion: The Geneva Law Exists. Russia Has Chosen Not to Abide by It.

A deliberate choice, not a misinterpretation

At the conclusion of this fact-check, one finding imposes itself with the cold clarity of legal texts: Russia is not making errors of interpretation of international humanitarian law. It is violating it deliberately, systematically, as part of a documented state policy. Convicting Ukrainian soldiers in uniform of "terrorism" for participating in military operations is a direct violation of Articles 4, 87, and 99 of the Third Geneva Convention. Maintaining detention conditions resulting in torture in 96% of cases is a violation of Articles 13 and 87 of the same Convention. These violations are not the work of uncontrollable local commanders: they are the work of national military tribunals, operating under federal authority, with a consistency and repetition that excludes any explanation other than political will.

Vladimir Putin ratified the Third Geneva Convention on behalf of the Russian Federation in 1954. He is not ignorant of these texts. He has read them, understood them, and decided they do not apply to his war. This is the choice of a leader who has never believed in the rule of law — not within his borders, nor beyond them. And it is precisely for this reason that he must be held accountable before the international mechanisms that the free world built, precisely, for such leaders.

What the West must do — now

Diplomatic condemnations are necessary — but insufficient. The pressure for ICRC access to Russian detention facilities must become a non-negotiable condition of any ceasefire agreement or any easing of sanctions. The Russian judges handing down these sentences — identified, named, documented — must be targeted by coordinated individual sanctions across the EU, the United States, the United Kingdom, and allies. The files transmitted to the ICC must be prioritized. And the 290 POWs convicted of "terrorism" must be named and individually included in all exchange lists, whatever Russia's objections about their internal criminal designation.

Zelensky is fighting for his soldiers with the diplomatic tools at his disposal. The free world must accompany him with the one thing Putin understands: real consequences. Not communiqués. Consequences. The Geneva Convention is not a pious wish. It is a binding treaty. And treaties have enforcement mechanisms — provided democracies have the will to use them.
