Russia said on Friday that it had shot down 221 Ukrainian drones overnight, one of the highest tallies of the more than three-year war.
Moscow’s defense ministry said its alert systems had “intercepted and destroyed” the drones, over half of which flew over the regions of Bryansk and Smolensk.
The figure included 28 aircraft downed over the Leningrad region, which surrounds the city of St Petersburg.
Leningrad governor Aleksandr Drozdenko said a fire had broken out on a vessel in the Port of Primorsk, a major facility on the Baltic Sea, following drone incursions in the region.
The attacks came after Poland, which borders Ukraine, accused Russia of launching a drone raid on its territory this week.
Moscow has denied targeting the country and said there was no evidence the drones were Russian.
But France and Germany moved to bolster the defense of Polish airspace, with the UN Security Council calling an emergency meeting to discuss the allegations.
Russia has targeted Ukraine with regular drone barrages as part of an ongoing offensive there following its 2022 invasion.
