School employees inspect a classroom damaged as a result of a missile attack in Lviv, western Ukrainian city, on February 15, 2024, amid the Russian invasion in Ukraine. Ukraine was under a nationwide air alert for over two hours on February 15, 2024 after the military warned that a group of bombers had taken off from a base in Russia. But it was lifted hours later, with the air force saying in a post on Telegram that the "missile threat is over". (Photo by YURIY DYACHYSHYN / AFP)
