"These people were killed by the Russians. This is a terrible loss. My condolences to their families and loved ones," said Tymur Tkachenko, head of the Kyiv Regional Administration

He said at least 13 people were injured, and there were fires in at least five other districts at residential buildings, cars, warehouses, offices and other non-residential structures

In a post on the Telegram messaging app, Kyiv mayor Vitali Klitschko said rescue workers were working at a residential building in Shevchenkivskyi District, after falling debris caused a fire on the top floor of an apartment building

Karyna Holf, 23, was in the living room near the window when she heard a whistling sound from the incoming weapon. A moment later, little was left of the room but debris

"After such a shock, when you know from your own experience what it`s like to lose everything," she said. "I don`t even know what comes next. All I have now is a backpack, a phone, and a winter coat, that`s it. This is my whole life now"

Holf said she was grateful to have her parents to turn to, but added, "There are people who have no one at all"
