Ukraine targeted Moscow with drones overnight, killing at least two people, Russian officials said on Sunday.
More than 180 drones had been intercepted, Russian state news agency TASS reported, citing Moscow Mayor Sergei Sobyanin.
Moscow’s regional governor, Andrei Vorobyov, said two people had been killed, and at least six others, including two children, injured.
It was not initially possible to independently verify the information.
The drone attack comes on the final day of Russia’s three-day parliamentary election that is set to confirm the dominance of Kremlin-loyal parties in the State Duma legislature in Moscow.
The Duma election, the first since Russia launched its full-scale invasion of Ukraine in February 2022, is seen as a referendum on the continuation of the war.
Critics had already branded the vote as unfair before it began, as the opposition has been barred from standing.
Russia has repeatedly attacked Ukrainian cities with ballistic and cruise missiles, glide bombs and drones. Ukraine, backed by Western military support, has responded with strikes on Russian territory, relying heavily on relatively cheap and rapidly produced drones as well as cruise missiles.
