Russia fired more than 100 drones at civilian areas of Ukraine overnight, authorities said Monday, as the Kremlin dismissed its transportation chief after a weekend of travel chaos when airports grounded hundreds of flights during the busy vacation season due to the threat of attacks from Kyiv. At least 10 civilians were killed and 38 injured, including three children, in Russian attacks over the previous 24 hours, Ukrainian officials said. Russia recently has intensified its airstrikes on civilian areas after more than three years of war.
