The Russian Defence Ministry say Ukraine launched a drone attack on Moscow, compelling flights to be diverted from Vnukovo International Airport.
The defence ministry said all the drones were shot down and there were no casualties or damage.
Tuesday’s attack saw not less than five drones reportedly used in the attack. The attack also hit some areas across the region around the capital.
However, Ukraine is yet to claim responsibility for the alleged attack.
Vnukovo is one of Moscow’s three international airports, with restrictions recently lifted. Flights from Turkey, the United Arab Emirates and Egypt were among those affected.
“An attempt by the Kyiv regime to attack a zone where civil infrastructure is located, including an airport that receives international flights, is a new terrorist act”, said Foreign Ministry spokeswoman Maria Zakharova in a statement on Telegram.
According to the defence ministry, four of the drones flying in the Moscow region were shot down by air defence systems. A fifth was intercepted electronically before crashing.
