INVESTIGATION: May 2026, deadliest month for Ukrainian civilians since April 2022

INVESTIGATION: May 2026, deadliest month for Ukrainian civilians since April 2022

Introduction: the figure that accuses — 274 dead in May, a tragic record

The UN confirms the heaviest toll in four years

On June 23, 2026, the UN released a report that should have made front pages around the world. In May 2026, at least 274 civilians were killed and 1,763 wounded in Ukraine. That is the highest combined monthly casualty toll since April 2022 — since the first months of the full-scale invasion, when Russia was still shelling Kyiv and the executions of Bucha had just been discovered.

Those figures came from UN Assistant Secretary-General Mohammed Khaled Khiari, who specified that they represent a minimum — "the actual figures are probably significantly higher." Behind each number lies a story, a family destroyed, a life torn away by bombs, missiles and drones that do not distinguish uniforms from children's dresses.

Four years of invasion: an astronomical humanitarian toll

The cumulative picture since February 24, 2022 is equally damning. The UN has counted a total of 16,126 confirmed civilian deaths, including 796 children, and 46,590 civilian wounded, including 2,835 children. Those confirmed figures represent the visible tip of a much larger iceberg — thousands of deaths in occupied territories inaccessible to observers, victims whose deaths will never be documented.

These data points are not abstract statistics. They represent people who were living ordinary lives in Ukraine — parents, students, pensioners, doctors, teachers — cut down by a war they did not choose. Ukraine did not attack Russia. It was Russia that crossed the border, that bombs, that kills.

The methodology of investigation: how the UN counts civilian casualties

Systematic documentation under impossible conditions

The work of the UN Human Rights Monitoring Mission in Ukraine (HRMMU) takes place under extraordinarily difficult conditions. Monitors must document casualties in active combat zones, often without direct access to strike sites. They cross-reference information from official Ukrainian sources, humanitarian organizations, journalists present in the field, and survivor testimony.

The UN's conservative methodology means that only cases with sufficient documentary evidence are included in official statistics. A civilian killed in an occupied village, with no accessible witnesses and no accessible official documentation, does not appear in the figures. That is why the UN itself acknowledges that its data represents minimums, not totals.

Occupied territories: the most troubling documentary void

The most difficult area to document remains the Russian-occupied territories — approximately 18% of Ukraine's internationally recognized territory. In those zones, UN monitors have had no access since 2022. Independent journalists are largely excluded. Information comes primarily from testimony of people who managed to flee to Ukrainian-controlled areas.

What is the scale of the atrocities committed in those occupied territories? We do not know precisely. Clues exist — mass graves discovered during territorial reconquests, testimony from freed deportees, intercepted communications. But systematic documentation remains impossible as long as Russia controls those zones and refuses any independent access.

The causes of the surge: the escalation of strikes in May 2026

Ballistic strikes on Ukrainian cities

The rise in civilian casualties in May 2026 is directly correlated with the intensification of Russian ballistic strikes on Ukrainian cities. On June 23, 2026, a Russian ballistic missile struck Kryvyi Rih, killing 4 people and wounding 30. That is not an isolated incident — it is the daily pace of a war deliberately targeting Ukrainian civilian populations.

Russian Iskander-M, Kinzhal and Oreshnik missiles are not weapons designed for surgical precision — their use against cities is a deliberate strategy of terror and population exhaustion. Russia does not only target military infrastructure: it targets markets, hospitals, shopping centers, bus stops packed with children returning from school.

Attacks on energy infrastructure and their civilian impact

Beyond the direct casualties from strikes, Russian attacks on Ukrainian energy infrastructure cause massive civilian suffering. Millions of Ukrainians spent the winter of 2025-2026 with regular power cuts, failing heating systems, hospitals running on generators. Those degraded conditions increase mortality in diffuse ways — elderly people dying of hypothermia, intensive-care patients whose equipment shuts down.

The strike of June 25, 2026 illustrates this reality: Russian attacks killed 7 people and wounded 70 others across Ukraine in a single day, targeting gas installations in several regions. Those strikes aim as much to terrorize the population as to degrade Ukrainian military capabilities.

The profile of victims: who dies in this war?

The 796 confirmed children: every number is a first name

Among the 16,126 confirmed civilian deaths, 796 are children. That figure — incomprehensible in its abstraction — represents babies, toddlers, teenagers whose entire lives lay ahead of them. They died in markets, in their homes, on school buses, in parks. They died because Russia decided to invade their country.

The Ukrainian government maintains a separate register of children killed, with as many names and details as possible. That work of remembrance is both a moral obligation and an act of resistance — against forgetting, against normalization, against the temptation to reduce lives to statistics. Every child in that register had a first name, parents, dreams, a future that was stolen from them.

The most affected regions

The regions most affected by civilian casualties are unsurprisingly those close to the front and the major cities regularly targeted. Donetsk oblast — of which Kostyantynivka, Kramatorsk and Sloviansk are recurring targets — concentrates a significant share of the victims. The oblasts of Kharkiv, Zaporizhzhia, Kherson and Mykolaiv are also heavily affected by artillery, missile and drone strikes.

Even Kyiv, relatively better protected by its air defense batteries, is not immune. Fragments from shot-down missiles and drones regularly fall on residential neighborhoods, causing casualties. The residents of the Ukrainian capital have been living for more than four years under the permanent threat of air alerts, packed shelters and the fear of not making it home.

The comparison with April 2022: what this escalation reveals

Why the comparison with 2022 is particularly damning

April 2022 is the month of the discoveries of Bucha, Borodianka, Hostomel — towns near Kyiv where retreating Russian soldiers had left behind evidence of extrajudicial executions, torture and other war crimes. The civilian toll that month was exceptionally high precisely because Russian forces had just withdrawn from areas they had occupied for several weeks.

That May 2026 surpasses that toll in combined casualties (killed + wounded) is therefore particularly alarming. It does not mean that Russia is now committing crimes worse than those at Bucha — those crimes remain in a category of their own — but that the intensity of strikes on civilian populations has reached and exceeded the levels of the first and most savage months of the war.

Deliberate escalation: Russia's strategy of exhaustion

That escalation is not accidental. It reflects a deliberate Russian strategy of civilian exhaustion — an attempt to break Ukrainian resistance by making daily life unbearable. If Ukrainians cannot defeat Russian forces on the battlefield, Putin calculates that sufficiently large civilian suffering might force the Zelensky government to negotiate unfavorable terms.

That calculation has a fundamental flaw: it assumes a passive, demoralized Ukrainian population ready to capitulate under pressure. Four years of war have proven the opposite. The more Russia bombs, the more Ukrainian resistance consolidates. The more suffering accumulates, the more hatred for the aggressor intensifies. Terror does not work against a people that has decided to fight for its existence.

The 68,900 war crimes registered in one year: the impunity gap

213,200 war crime episodes since 2022: an overwhelming figure

Ukrainian prosecutors registered 68,900 new war crimes between June 2025 and June 2026, bringing the total to more than 213,200 episodes since the start of the full-scale invasion. Those crimes include deliberate strikes on civilians, summary executions, documented torture, forced deportation of children — all acts that constitute serious violations of international humanitarian law.

That register is the result of a titanic effort by Ukrainian prosecutors, with the support of the International Criminal Court (ICC), the UN, and numerous human rights organizations. It forms the documentary basis for potential criminal prosecutions — and it will be irrefutable historical proof of what Russia has done to Ukraine.

Only 97 convictions: the chasm between documentation and justice

Despite those 213,200 documented episodes, only 97 convictions have been handed down — and most of them by default, against defendants who never appeared before a court. Ukraine's own prosecutor general described that outcome as "insufficient." That is a spectacular understatement: the ratio between documented crimes and actual convictions is approximately 1 in 2,200.

That impunity gap is not due to a lack of will — Ukrainian prosecutors are working under wartime conditions with limited resources. It reflects the structural reality of international justice: slow, complex, dependent on state cooperation and enforcement mechanisms that do not yet exist to sanction an aggressor state.

The strikes that defined May 2026

Kryvyi Rih, Kharkiv, Zaporizhzhia: cities under repeated strikes

Kryvyi Rih, President Zelensky's hometown, has been struck multiple times. A ballistic strike on June 23, 2026 killed 4 people and wounded 30 — and that is just one example among dozens. Kharkiv, Ukraine's second city, suffers near-daily bombardments due to its proximity to the Russian border, less than 40 kilometers away. Zaporizhzhia, within range of Russian positions, is also a regular target.

Those repeated strikes have a dual objective: to destroy civilian infrastructure that supports urban life and the war effort, and to create a continuous flow of refugees that exhausts the resources of still-safe zones and European host countries. Russia's forced migration policy — turning millions of Ukrainians into refugees — is itself a weapon of war.

Strikes on demining teams

Russian brutality does not stop at city bombardments. On June 25, 2026, a Russian strike killed two members of a demining team from a Norwegian charitable organization in Kherson oblast, wounding four others. Those volunteers were risking their lives to clear mines and make Ukrainian agricultural land usable again.

Deliberately targeting humanitarian demining teams constitutes a direct violation of the Geneva Conventions. It also illustrates the cynical calculus of Russian strategy: keep Ukraine in a state of permanent insecurity, even in liberated zones, by sowing mines and preventing their removal. The mine contamination left by Russia will kill and maim Ukrainians for decades after the fighting ends.

The Ukrainian response: striking to protect

The 40-day strategy as a response to civilian losses

The 40-day operation approved by Zelensky on June 25, 2026 is in part a direct response to those growing civilian losses. By striking the Russian refineries that fuel the bombers, the fuel depots that supply missiles and drones, the factories that manufacture weapons — Ukraine is seeking to reduce at the source Russia's ability to strike its cities.

That deep-strike strategy is both defensive and offensive. It aims to exhaust the Russian war machine before it reaches Ukrainian cities. From the refineries of Ufa to the missile factories of Volgograd, every Ukrainian strike on the Russian military-industrial complex is potentially one fewer missile on a Ukrainian city.

The 660 drones of the night of June 25-26: a show of force

During the night of June 25 to 26, 2026, Ukraine launched its largest drone wave since the start of the war — at least 660 aircraft targeting 13 Russian regions, including Moscow, Tula and occupied Crimea. An industrial installation in Novomoskovsk was damaged. The Azot chemical plant — a producer of explosive components — was targeted.

That record wave is a direct message from Kyiv to Moscow: if you keep striking our cities, we will strike yours. This is not vengeance — it is deterrence. And unlike Russian strikes on Ukrainian markets and hospitals, Ukrainian strikes target the Russian military-industrial complex, war factories, military energy infrastructure.

The humanitarian situation: 4 million displaced across Europe

The Ukrainian diaspora: refugees or eligible for mobilization?

More than 4 million Ukrainians are currently displaced in Europe under temporary protection. That diaspora is the subject of growing political debate, particularly since Denmark announced on June 25, 2026 that it would no longer extend protection to Ukrainian men of draft age — those aged 23 to 60. That decision precedes a European Commission proposal to exclude men subject to military obligations from the temporary protection granted to refugees.

Those measures create a real ethical and legal dilemma. On one side, Ukraine needs soldiers and the Zelensky government has implemented a travel ban for men eligible for mobilization. On the other, forcing men in Europe to return to fight in a war from which they fled conscription raises refugee protection questions that international law did not anticipate.

Internally displaced: 6 million still in Ukraine

In addition to the 4 million abroad, approximately 6 million Ukrainians remain internally displaced within their own country — having fled combat zones for other Ukrainian regions. Those people often live in precarious conditions, dependent on humanitarian aid, in regions where they have no established social networks.

The question of return remains conditional on safety in liberated zones. Mine contamination, infrastructure destruction, the presence of snipers and enemy units in officially liberated areas all complicate the return of displaced people. Dozens of liberated villages in Kherson or Kharkiv oblast remain at risk from mines and long-range artillery strikes.

The role of humanitarian organizations in the Ukrainian inferno

The Red Cross, UNHCR and NGOs in the field

Dozens of humanitarian organizations operate in Ukraine despite considerable risks — Médecins Sans Frontières, the International Committee of the Red Cross, the UNHCR, national and local organizations. They provide emergency medical care, food aid, emergency shelter and psychological support to survivors. Their work is essential and undervalued in narratives focused on military operations.

The strike on the Norwegian demining team on June 25, 2026 is a reminder that those organizations are not safe from Russian strikes. Working in conflict zones involves risks that volunteers accept with full knowledge — but to those risks should never be added the risk of being deliberately targeted by an army.

International humanitarian aid: insufficient given the scale of needs

International humanitarian aid to Ukraine — while significant in absolute value — remains insufficient given the scale of the destruction. Millions of people lack running water, reliable heating, regular medical care. Hospitals have been running on generators for months. Drinking water systems in entire cities have been destroyed by deliberate strikes.

Rebuilding that infrastructure will require tens of billions of euros and years of work — once the war is over. In the meantime, millions of Ukrainians are living in conditions that their grandparents, survivors of World War II, would have recognized with a painful familiarity. The word "resilience," so often applied to Ukrainians, is a beautiful way of saying that ordinary people are enduring the unimaginable.

International justice: where does the ICC stand?

Arrest warrants against Putin and others

The International Criminal Court issued arrest warrants against Russian President Vladimir Putin and children's rights commissioner Maria Lvova-Belova in connection with the forced deportation of Ukrainian children to Russia. Ukraine accuses Russia of having deported tens of thousands of children from occupied territories — an accusation now under examination by international investigators.

Those warrants cannot be directly enforced — Russia is not party to the Rome Statute and does not recognize the ICC's jurisdiction. But they have important symbolic and practical value: they restrict Putin's freedom of movement across the 124 member states of the ICC (even if several, like South Africa at the BRICS summit in 2023, chose not to enforce the warrants).

The 97 convictions and the prospect of an ad hoc tribunal

The gap between the 213,200 documented crimes and the 97 convictions has led several experts and governments to call for the creation of a special tribunal for crimes of aggression against Ukraine — a mechanism complementary to the ICC, which has limited jurisdiction over the crime of aggression itself. That proposal, championed notably by the Baltic states and Poland, faces resistance from some major countries that fear setting a precedent.

In the meantime, the documentation work continues. Every documented crime is a piece of evidence preserved for the future. The history of World War II teaches that justice can come decades after the events — and that meticulous documentation of crimes is the prerequisite for any future prosecution.

The psychological impact on Ukrainian society

Collective trauma and resilience: the dual reality

Four years of war have left deep scars on Ukrainian society. Millions of people suffer from post-traumatic stress, chronic anxiety, unprocessed grief. Children who have known nothing but war, whose ordinary life has unfolded between air alerts and shelters. Soldiers who come home — when they come home — with physical and psychological wounds that overwhelmed healthcare systems struggle to treat.

And yet, Ukrainian society continues to function, to create, to resist. Theaters perform in Kyiv. Entrepreneurs open restaurants. Artists exhibit. Couples marry. That life continuing coexists with grief, fear and determination — a harrowing coexistence that is perhaps the most accurate definition of what it means to "hold on."

The children of war: a wounded generation

The generation of children growing up in Ukraine since 2022 will carry the weight of this war for the rest of their lives. Studies show that children exposed to armed conflict display high rates of anxiety disorders, learning difficulties and socialization problems. Those effects can last a lifetime without appropriate psychological intervention.

Ukraine is investing in psychological support for children — with the help of international organizations and local specialists. But resources are limited and needs are immense. The reconstruction of post-war Ukraine will need to include large-scale psychological reconstruction — a challenge as important as the physical reconstruction of infrastructure.

Humanitarian aid in figures: what is being done, what is missing

Contributions from international organizations since 2022

Since the start of the invasion, billions of dollars have been mobilized in humanitarian aid for Ukraine. The World Food Programme, UNICEF, the UNHCR and hundreds of national and international NGOs have provided food, emergency shelter, medical care and psychological support to millions of people. That collective effort is remarkable — and insufficient given the scale of the destruction.

The G7 has disbursed a total of $45.5 billion in loans to Ukraine, funded by the interest on frozen Russian sovereign assets. Those funds partly cover humanitarian needs, but the pressure of military expenditures often leaves humanitarian programs underfunded. The ratio between military aid and humanitarian aid remains heavily skewed toward the military.

The challenge of distribution in combat zones

Even when funds exist, distributing aid in areas close to the front represents an enormous logistical challenge. Roads are destroyed, bridges bombed, humanitarian corridors contested by Russian forces. Aid convoys have been targeted on multiple occasions. Organizations operating in those conditions do so at the risk of their lives.

The strike on the Norwegian demining team on June 25, 2026 in Kherson oblast illustrates that mortal risk. Two team members were killed, four wounded — volunteers who dedicated their lives to making Ukrainian land habitable. Russia killed them. That crime must be documented and prosecuted.

The international community must invest equally in humanitarian aid, not only in weapons. Protecting Ukrainian civilians requires both.

The 69,000 war crimes and the challenge of truth

How to preserve memory against Russian propaganda

Russia systematically denies having targeted civilians — all its strikes are presented as "legitimate military targets." That propaganda, effective with certain non-Western audiences, seeks to create a narrative ambiguity around the reality of the crimes committed. It is precisely to counter that manipulation that meticulous documentation of war crimes is strategically essential.

Organizations like Bellingcat, the Centre for Information Resilience and dozens of Ukrainian and international entities document civilian strikes with geolocated evidence, satellite imagery analysis and verified videos. That truth-work is a form of resistance as important as drone strikes.

The responsibility of international media

International media coverage of this war has been, on the whole, serious — but with troubling gaps. "War fatigue" in some newsrooms sometimes leads to treating the 274 civilians killed in May 2026 as secondary news, buried in the daily flow. Every time a civilian toll is relegated to an inside page, an implicit normalization of the horror takes place.

Ukrainian journalists themselves — several of whom have been killed since 2022 — play an irreplaceable role in that coverage. Their presence in the field, their knowledge of context, their personal commitment make their work indispensable. Supporting them — financially, logistically, politically — is a responsibility that international media assume unequally.

Conclusion: the figures demand a response

274 deaths in May: a call to action, not a statistic

The May 2026 toll is not just another news item. It is an alarm signal that should provoke a stronger response from the international community. More air defenses delivered, more quickly. More diplomatic pressure to force Russia to stop targeting civilian areas. More resources for the investigators documenting war crimes. More funding for psychological support for survivors.

At the Ankara summit, the €70 billion promised cannot be limited to weapons. They must include a substantial humanitarian component, support for the reconstruction of destroyed infrastructure, funding for demining teams who risk their lives to make Ukraine habitable. Protecting Ukrainian civilians is as urgent as military victory.

The West's moral countdown

Every day the West takes to deliver promised weapons, to pass announced budgets, to implement decided sanctions, is one more day during which Ukrainians are dying with insufficient resources. That is not an accusation — it is a fact. Democracies are slow by design. But democratic slowness carries a human cost that UN figures measure with cold precision.

The 274 civilians killed in May 2026, the 16,126 since the beginning, the 796 children — those figures will not disappear with the end of the war. They will remain as testimony to what happened when a democracy resisted a dictatorship, when free peoples had to choose how far they were prepared to go to defend an attacked neighbor. History will judge our choices.

Columnist's transparency note

My sources and my method

This article relies on data published by the UN via Ukrpravda, Euromaidan Press reports on war crimes, and Kyiv Independent data on recent strikes. I do not have access to the complete HRMMU databases nor to Ukrainian prosecutors' case files — my information comes from official communiqués and journalistic reporting.

The figures I use are those provided by the UN and Ukrainian authorities. I report them as such, noting that the UN itself specifies that they represent minimums. I do not compare, minimize or nuance those figures in the interest of any kind of moral equivalence. Russia is bombing Ukrainian civilians — it is documented, it is real, and it is a crime.

My acknowledged biases

I am pro-Ukrainian and I remain so without apology. That does not mean I ignore the complexities of this conflict or that I present an idealized image of Ukraine. It means that faced with illegal aggression and documented war crimes, I refuse the neutrality that would itself be a form of complicity. Ukraine was attacked. Its civilians are being killed. Those realities are not open to interpretation.

I acknowledge not knowing exactly how many civilians have been killed in the inaccessible occupied territories. I do not know the precise toll of every individual strike. Those epistemic limitations are real, and I hope readers understand that I work with available information, not with an omniscience I do not possess.
