Russian authorities said on Friday that 51 drones were shot down over the Leningrad region in an overnight attack near Ust-Luga, a key oil export hub.
Leningrad Governor Alexander Drozdenko said on Telegram that authorities initially announced a drone threat across the region as air defence operations got under way.
He later said that 15 "enemy" drones had been downed, with the number subsequently rising to 37 as operations continued.
In a further update, Drozdenko said a total of 51 drones had been shot down over the Leningrad region.
"As a result of the damage, a fire was recorded in the port of Ust-Luga," he said. "Experts began extinguishing the fire. The fighting continues."
The governor later announced that the drone threat had been eliminated.
The attack comes amid an intensifying Ukrainian campaign targeting Russian energy and military infrastructure deep inside the country.
Ust-Luga, one of Russia’s largest Baltic ports and a major hub for crude oil and petroleum product exports, has been repeatedly targeted in recent months.
The latest strike follows attacks this week on the Orsk and Gazprom Neftekhim Salavat refineries, as Kiev seeks to disrupt infrastructure supporting Russia’s economy and war effort.
