Two drones launched by Russian forces into Ukraine's Odesa region struck military objects, causing a fire and the detonation of ammunition, the South Command of Ukraine's forces said on Monday.

"As a result of a large-scale fire and the detonation of ammunition, the evacuation of the civilian population was organized," the command said in statement on the Telegram. "Preliminarily, there have been no casualties."

There has been no response from Russia.
