KYIV, Ukraine (AP) — Russian forces fired cruise missiles at the southern Ukrainian city of Odesa overnight, killing at least three people and injuring more than a dozen others in a strike that damaged homes, a warehouse, shops and cafes downtown, 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 defenses, the regional administration said on Facebook.

Three employees of a food warehouse were killed and seven others injured, and searchers were looking for possible survivors under the rubble, it said. Another six people — guards and residents of a neighboring house — were injured.

Andriy Kovalov, a spokesperson 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 counteroffensive.

In a briefing, he said strikes on the Kharkiv, Donetsk, 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.
