MOSCOW, Dec. 12 (Xinhua) -- Russian air defense systems shot down over a dozen Ukrainian drones targeting Moscow on Friday, the city's Mayor Sergei Sobyanin said.
Sobyanin posted updates on social media in the day about defense forces destroying unmanned aerial vehicles flying toward the Russian capital, recording at least 13 drones downed.
The drone attacks have affected the civilian air traffic in Moscow. Authorities imposed a temporary restriction on flights for about an hour at three Moscow airports on Friday morning.
The Russian Defense Ministry said Friday that the air defense had downed 90 Ukrainian drones overnight across multiple regions, including four over the Moscow region.
Meanwhile, the ministry added, the Russian side carried out a series of strikes against targets in Ukraine over the past week, in response to alleged Ukrainian attacks on civilian facilities in Russia.
It said in a statement that the Russian attacks included one massive strike and five group strikes, some of them involving Kinzhal aeroballistic hypersonic missiles.
The strikes hit enterprises and their supporting fuel and energy facilities in Ukraine's military industry, as well as transport, airfield and port infrastructure used in the interests of the Ukrainian armed forces.
The Russian military said the strikes also targeted facilities involved in the assembly, storage, pre-flight preparation and launch of long-range combat drones, along with fuel depots and warehouses storing military and technical equipment.
The targets also included temporary deployment points of Ukrainian armed formations and foreign fighters, said the statement. ■
