Russian forces fired cruise missiles at the southern Ukrainian city of Odessa overnight, killing at least three people and injuring more than a dozen others in a strike that damaged homes, a warehouse, shops and cafes, the regional state administration said.
The attack, launched from the Black Sea, involved four sea-launched Kalibr cruise missiles, three of which were intercepted by air defences, the regional administration said on Facebook.
Three employees of a food warehouse were killed and seven others injured, and rescuers were searching for possible survivors under the rubble, it said.
A further six people - guards and residents of a neighbouring house - were injured.
Andriy Kovalov, a spokesman for Ukraine's General Staff, said Russian forces have increased missile and aerial strikes on Ukraine.
It comes as Kyiv moves forward with the early stages of a counter-offensive.
In a briefing, he said strikes on the Kharkiv, Donetsk and Kirovohrad regions, in addition to the Odesa region, involved Kh-22 cruise missiles, sea-launched Kalibr cruise missiles, and Iranian-made Shaheed drones. Nine were intercepted.
