The death toll has risen to at least four people and nine others are injured following a Russian missile strike in the western city of Lviv Thursday, Ukrainian officials said.

The missile directly hit an apartment building, destroying the third and fourth floors, Ukraine's Minister of Internal Affairs, Ihor Klymenko, said on Telegram.

People are still trapped under the rubble and rescue efforts are ongoing, he said. So far, seven people have been rescued and 64 evacuated, he added.

President Volodymyr Zelensky offered his condolences to the victims' families and vowed to respond to the attack.

“There will definitely be a response to the enemy. A tangible one,” Zelensky said in a Telegram post.
