For the third time in just over a week, Moscow has shut down major airports as a result of Ukrainian drone strikes on the Russian capital.

State officials temporarily shut down three major airports near Moscow following a drone attack early Saturday morning, Russian state media reported. Officials closed Vnukovo, Sheremetyevo and Domodedovo airports, which provide domestic and international flights for civilians.

While officials with the Russian Defense Ministry said Ukraine was behind the attack, Ukrainian authorities have yet to confirm, according to the Associated Press.
