A Ukrainian drone strike killed one person and wounded at least three others in southern Russia, regional authorities said Saturday, while nearly 100 people were fighting to extinguish a fire caused by the attack.

The strike damaged port installations in the Temryuk district on the Sea of Azov, near the Kerch Strait, which separates mainland Russia from the Crimean peninsula, which has been occupied by Moscow since 2014.

“As a result of falling drone debris, a fire broke out at a maritime terminal... one person was killed,” Krasnodar region Governor Veniamin Kondratyev posted on Telegram.

He added that, according to initial reports, at least three people were wounded and that 96 people had been drafted to fight the blaze.

The Russian army said it had shot down a total of 177 Ukrainian drones overnight.
