Russian airstrike hits busy shopping mall in central Ukraine, sparking fears of mass casualties - CNN

"Another 36 people are missing," he said, adding that more than 1,000 people -- including rescuers, police, medics and volunteers -- worked through the night.

"We continue the search."

Ukrainian President Volodymyr Zelensky said after the strike that up to 1,000 people were in the mall before the air raid was announced.

"Fortunately, as far as we know, at that time, many people managed to get out, they managed to get out, but there were still people inside -- workers and some visitors," he said.

At least 58 people were injured, according to Ukraine's State Emergency Services, while Lunin said 25 people were admitted to intensive care at the hospital in Kremenchuk.

Video from the scene showed heavy smoke billowing from the building, which was engulfed by fire.

It came as G7 leaders met at a summit in Germany that was mostly geared toward coordinating the Western response to Russia's invasion.

British Prime Minister Boris Johnson said from that meeting that the attack showed the "depths of cruelty and barbarism" of Russian President Vladimir Putin, the UK's PA news agency reported.
