KYIV, Ukraine — 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.

Russia and Ukraine struck each other with hundreds of drones on Sunday, throwing Russian air travel in disarray, days after Moscow launched its largest aerial assault in the more than 3-year-old war.

The Russian forces attacked Ukraine with 157 UAVs and 4 S-300 missiles on the night of 5-6 July. Ukraine's Air Force has reported that 98 drones were shot down and another 19 disappeared from radar. Source: Air Force of the Armed Forces of Ukraine Details: Russian drones struck 19 locations,
