A regional police department in Kharkiv was engulfed in flames on March 2 following a missile strike on Ukraine's second-largest city. 

Firefighters were seen battling the blaze as part of the structure collapsed. It was not immediately clear if there were any casualties in the strike on the police station.

At least 21 people were killed and 112 wounded in shelling in Kharkiv in the last 24 hours, regional governor Oleg Synegubov said on Wednesday.
