The strike occurred in the northern Russian region of Novgorod for the first time since the start of the war.
Moscow has accused Kyiv of carrying out a drone attack on a military airfield in the Novgorod region in northern Russia.
Over the last few months, Russia has repeatedly accused Ukraine of striking targets within Russian territory for which Kyiv does not usually claim direct responsibility.
The Novgorod region lies between Moscow and St. Petersburg and has not been targeted since the start of the war, unlike Russia’s border regions.
On Saturday, the Russian defense ministry said that at around 10 a.m., Kyiv had carried out a “terrorist attack” using the a “helicopter-type” drone.
Local media reported that the airfield targeted in the attack was in the town of Soltsy, around 50 miles southwest of the region’s capital, Veliky Novgorod.
