According to Russia, a Ukrainian drone hit a train station in the Kursk area, wounding five people.
Another drone is claimed to have landed in the Rostov area, which, like Kursk, shares a border with Ukraine, although no injuries have been recorded.
Russia also stated that it intercepted a drone on its way to Moscow, which crashed in an unpopulated location.
Allegations of drone strikes within Russia have been more regular in recent months.
Despite the fact that Ukraine has not claimed credit for particular drone operations, President Volodymyr Zelensky has previously stated that assaults on Russian territory are a “inevitable, natural, and absolutely fair process.”
The BBC confirmed footage of damaged glass and a fire blazing at the Kursk train station, which is around 150 kilometers (93 miles) from the Ukrainian border.
Glass pieces injured five persons, according to Russia’s RIA Novosti news agency. The station’s roof, façade, and platform were all destroyed.
The Russian Foreign Ministry has stated that it “strongly condemns” the drone assault on Kursk.
“Ukrainian nationalists literally dealt a blow to our common history,” said ministry spokesperson Maria Zakharova.
In its own statement, Russia’s defense ministry said it had “thwarted” an “attempt by the Kyiv regime to carry out a terrorist attack by drone on infrastructure in Moscow” around 04:00 local time (01:00 GMT).
The Moscow-bound drone was destroyed by “electronic warfare” before losing control and crashing in an unpopulated area, the ministry added.
Flights to Russia’s international airports Domodedovo and Vnukovo were “temporarily limited” as a result, according to Rosaviatsia.
It comes after a Russian missile attacked a theater in the northern Ukrainian city of Chernihiv on Saturday, killing seven people, including a six-year-old child.
According to authorities, fifteen children were among the 148 persons injured.
President Zelensky promised a “tangible response to Russia for this terrorist attack.”
