According to the UN Human Rights Monitoring Mission in Ukraine (HRMMU), more than 30 locations across seven districts of Kyiv were struck in what it described as “the deadliest attack” on the Ukrainian capital in nearly a year.

“Last night’s attack exemplifies the grave threat posed by the tactic of deploying missiles and large numbers of drones simultaneously into populated areas,” said Danielle Bell, Head of HRMMU.

Humanitarian Coordinator for Ukraine, Matthias Schmale, also strongly condemned the attacks, which extended to Odesa, Zaporizhzhia and other areas.

“The people of Ukraine should not have to take cover in shelters night after night,” he said. “Each day, the war takes a devastating toll on civilians.”

In the southern port city of Odesa, strikes reportedly injured several civilians and damaged a kindergarten and a centre for children with special needs – places where children should feel safe. In Zaporizhzhia, residential buildings were hit.

First responders and humanitarian agencies are already on the ground, providing emergency care and supplies while assessing further needs.

Human toll rising

The barrage included 440 long-range drones and 32 missiles launched by Russian forces, HRMMU noted in a news release citing information from Ukrainian authorities, of which 175 drones and 14 missiles targeted Kyiv.

It marked the fourth time this month that more than 400 munitions were fired in a single night – far surpassing the 544 total launched during the entire month of June 2024.

Even before this latest attack, the human toll of such tactics had been rising sharply. HRMMU had already verified at least 29 civilian deaths and 126 injuries from long-range weapons in June alone.

The overall civilian casualty count in the first five months of 2025 is nearly 50 per cent higher than in the same period last year.

Mr. Schmale reiterated that attacks on civilians and civilian infrastructure are prohibited under international humanitarian law.

“Civilians, including children, must never be a target,” he said. “We must not normalize the war.”

Refugee crisis deepens

Meanwhile, the broader humanitarian crisis continues to deepen. The intense conflict, now in its third year since Russia’s full-scale invasion, has driven more than 6.3 million Ukrainians to seek refuge across Europe.

Most are women, children, and older persons, many of whom rely on temporary protection directives extended by host countries like the European Union (EU) and Moldova, according to a report released on Tuesday by Office of the UN High Commissioner for Refugees (UNHCR).

Noting the volatile situation in Ukraine, the agency urged the respective governments to maintain legal status for refugees until conditions allow for safe, dignified, and sustainable returns.
