Russia says Ukraine has launched an overnight drone attack targeting Moscow for the second night in a row. All four of the capital's major airports have been closed temporarily to ensure safety, Russia's aviation watchdog Rosaviatsia said on Telegram. Moscow's mayor, Sergei Sobyanin, said on social media at least 19 Ukrainian drones had been destroyed before they reached the city "from different directions". He said some of the debris had landed on one of the key highways into the city, but there were no casualties. Ukraine has not yet commented on the reports
