At least three people are dead following a Ukrainian drone attack on the Engels bomber base in southern Russia, according to Moscow
According to reports, air defenses fired down the drone, but the victims of the midnight attack were caused by falling debris.
The airbase, which houses strategic bombers, was the target of a similar strike from Ukraine, according to Russia, on December 5. The base is located roughly 500 kilometers (310 miles) northeast of the Ukrainian border.
Official comments regarding those attacks have not been made by the Ukrainian military.
The Ukrainian drone was shot down by Russian air defenses, according to the Russian defense ministry, at around 01:35 local time on Monday (22:35 GMT Sunday).
Drone debris injuries claimed the lives of three Russian service members.
Social media users earlier shared videos of what appeared to be blasts and air sirens at the Engels airstrip.
There was "no threat to citizens" of the town of Engels itself, according to the governor of the Saratov region.
Three servicemen were also killed by drone debris in the previously reported attack on the airfield and another air facility in the Ryazan region on December 5, Moscow claimed at the time. Two airplanes suffered minor damage.
The purported attacks received no response from the Ukrainian military.
Since Moscow began its full-scale invasion on February 24, the Russian military has frequently launched missile attacks on numerous targets in Ukraine from the Engels air base.
The Kremlin has previously accused Ukraine of striking Russian territory, but the purported attacks in December are reportedly more severe.
The reported strikes, according to a number of military analysts in the West and Ukraine, were embarrassing for the Russian military.
