Russia launched 42 drones and 6 missiles at Ukraine's southern regions overnight with air defences destroying 41 drones, but missiles killed one civilian, Ukrainian military said on Sunday.

"The defenders of the sky managed to shoot down 41 out of 42 Shahed-136/131 attack drones. The vast majority of them were shot down in Odesa region," Ukrainian Air Force said on the Telegram messaging app.

Reuters could not independently verify the air force's report. There was no immediate comment from Russia.

Ukrainian military said wreckage of downed drones damaged more than a dozen buildings in the southern city of Odesa and 11 civilians, including three children, were injured.

Emergencies services said that during an overnight missile strike on the neighbouring Kherson region, one person was killed and a medical facility, private house and garage were destroyed.

The military also said Russia attacked port infrastructure in the Danube region and debris damaged the warehouses of two grain storage facilities.
