Russian drones attacked Ukraine's Black Sea port of Odesa overnight, killing one person and injuring 13 others, including two boys, regional governor Oleh Kiper said on Saturday, Paralel.Az reports citing Reuters.

Several residential apartment buildings, private houses, commercial buildings and dozens of private cars were damaged in what was the second day in a row of Russian drone attacks on the city, Kiper said.

"At night the enemy again attacked Odesa and the nearby region with attack drones. One person died and 13 were wounded. Among the injured there were two children," he said on the Telegram messaging app.

Prosecutors said the children were boys aged four and 16.

Russia launched 51 drones, focusing its attack on Odesa and the nearby region in the south of Ukraine, the Ukrainian air force said, adding that Ukrainian air defence units and mobile drone hunter groups shot down 32 Russian drones.

It also said that 18 drones were "lost", most likely meaning they had been thwarted electronically.

Russian drones also triggered a large fire in one of Odesa's districts, public broadcaster Suspilne reported, quoting residents.
