KYIV, Ukraine: Iranian-made kamikaze drones attacked Ukraine's capital region early Thursday. Officials said rescuers were dispatched to the spot.
Kyiv regional governor Oleksiy Kuleba said the strike occurred around the capital. It was not yet clear if there were any casualties.

"Critical infrastructure facilities" in the area where the attack took place were hit, without offering any details on which ones, Kerilo Tymoshenko, deputy head of the Presidential Office, said in a telegram.

In the southern city of Mykolaiv, overnight shelling destroyed a five-story apartment building.

An 11-year-old boy was rescued from the rubble in Mykolayiv, and rescuers were still searching for seven more on Thursday morning, Mykolayiv Regional Governor Vitaly Kim said.

He added that the building was hit by an S-300 missile, which is commonly used to target military aircraft.

Attacks on Kyiv had become rare before the capital city was hit at least four times during Monday's massive strikes, which killed at least 19 people and wounded more than 100 across the country.

Western leaders this week pledged to send more weapons to Ukraine, including air defence systems and weapons Kyiv has said are critical to defeating the invading Russian forces.

Britain said Thursday that it would provide missiles for advanced NASAM anti-aircraft systems that the Pentagon plans to send to Ukraine in the coming weeks. It's also sending hundreds of additional aerial drones for information gathering and logistics support, plus 18 more howitzer artillery guns.
