Russian missile and drone strikes killed at least 15 people and wounded dozens more in Kyiv and the surrounding region overnight, authorities said Wednesday, the latest in a wave of deadly attacks on Ukraine.

Kyiv has in recent months urged allies to supply more US-made Patriot interceptors as Russia steps up its use of ballistic missiles more than four years into its full-scale invasion.

Explosions were heard in Kyiv after midnight following Ukrainian air force warnings of incoming ballistic missiles.

Kyiv’s military administration said the missile and drone barrage slammed into residential buildings and several warehouses.

“The enemy is once again deliberately striking civilians and civilian infrastructure,” it said on Telegram.

The military administration reported one woman killed and at least 24 other people wounded in the capital after strikes sparked fires in four districts.
