Moscow said on Tuesday that Ukraine had fired six U.S.-made ATACMS ballistic missiles, six UK-made Storm Shadow cruise missiles and at least 146 drones into Russia in an attack that it said would not go unanswered.

Flight restrictions were imposed at five airports in Russia after Ukraine unleashed an attack reportedly with more than 200 drones and ballistic missiles. Alexander Bogomaz, the governor of the Bryansk region in western Russia, said Ukraine had launched a major missile attack but did not say which missiles had been used.

Ukraine launched a large-scale drone and missile barrage overnight, damaging factories, a chemical plant and a gas tank in Russia, according to local reports. Newsweek reached out to the foreign ministries of Russia and Ukraine for comment via email on Tuesday.
