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 were closed for several hours to ensure safety but later reopened, 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. But the mayor of Kharkiv said Russia had also carried out drone strikes in the city overnight, as well as in the Kyiv area.
