A Russian drone attack on a police building in northern Ukraine has killed two police officers, Ukraine's national police said on Wednesday.
The police said at least 20 other people were injured in the attack on the national police building in the city of Zhytomyr.
Russia used jet-powered drones in the attack, which caused a fire to break out on the roof and on the fourth floor, according to the police.
Ukraine has been defending itself against a full-scale invasion for nearly four and a half years.
