A Ukrainian drone attacked the headquarters of Russia’s FSB state security service in Russia’s Belgorod region on Wednesday, the Tass news agency reported.
The building was damaged in the incident but there were no casualties, it said.
Ukrainian drones struck targets in several Russian regions for the second night in row, officials said on Wednesday, again targeting energy facilities and setting at least one refinery on fire.
“The Ryazan oil refinery was attacked by a UAV,” Pavel Malkov, governor of the Ryazan region that borders the Moscow region to its north, said on the Telegram messaging app. “A fire broke out as a result.”
