Watch: Rocket fire destroys Lviv residential block

A Russian rocket has hit an apartment building in the western Ukrainian city of Lviv, killing at least four people, officials say.

Ukraine's Interior Minister Ihor Klymenko said more than 30 other people were injured and Lviv Mayor Andriy Sadovyi said it was "one of the biggest attacks" on the city's civilian infrastructure.

Drone footage posted by Ukraine's President Volodymyr Zelensky shows extensive damage to the building.
