The flight restrictions were lifted later in the morning."Much of the information on strike targets in Russia have come through Telegram and social media channels, and have remained unconfirmed on an official level, but various videos suggest a very large-scale attack.For example, Sky News reports that "Another post claimed a factory producing electronics for Russian missiles had been struck in Voronezh, more than 100 miles from Ukraine."All Moscow airports have been closed down due to drone attacks.
