Ukrainian President Volodymyr Zelenskyy said Friday that a Russian missile attack on a Kyiv apartment building the previous day killed 24 people, including three children.

Emergency workers finished digging through the building’s rubble after more than a day, Zelensky said on X.

The cruise missile hit the nine-story corner block during what the Ukrainian air force said was Russia’s biggest barrage of the country since its all-out invasion.

The assault mostly targeted the Ukrainian capital, where 48 people were wounded, including two children, Zelensky said.

Russia hammered Ukraine with large-scale aerial attacks in the days following a May 9-11 ceasefire that US President Donald Trump said he asked Zelensky and Russian President Vladimir Putin to observe. 

Fighting went on over those 72 hours, although reportedly on a lesser scale.

This week’s attacks ran counter to recent suggestions from Trump and Putin that the war, now in its fifth year, is close to ending.

Zelensky said Thursday that Moscow had launched more than 1,560 drones against Ukrainian population centers since Wednesday.

In all, some 180 sites across the country were damaged, including more than 50 residential buildings, he said.

Previously, the biggest Russian drone attack was from the evening of March 23 to the evening of March 24 when Moscow’s forces fired nearly 1,000 drones and missiles at Ukraine.

The Ukrainian capital observed an official day of mourning Friday in remembrance of those killed.

The cruise missile that hit the apartment building was built in the second quarter of this year, Zelensky said, apparently after Ukrainian experts analyzed the wreckage.

“This means Russia is still importing the components, resources, and equipment necessary for missile production in circumvention of global sanctions,” Zelensky said in another post on X late Thursday.

“Stopping Russia’s sanctions evasion schemes must be a genuine priority for all our partners,” he said.

Russia and Ukraine have continued to occasionally swap prisoners of war, and 205 from each country returned home Friday.

Zelensky said it was the first phase of a planned 1,000-for-1,000 prisoner swap. Some of the Ukrainians released had been held in Russian captivity since 2022, he said, and had fought in some of the war’s fiercest battles.

Russia’s Defense Ministry confirmed the exchange and thanked the United Arab Emirates for helping broker it.
