Russia fired more than 100 drones at civilian areas of Ukraine overnight, authorities said Monday, as the Kremlin dismissed the country's transport chief after a weekend of travel chaos when Russian airports grounded hundreds of flights due to the threat of Ukrainian drone attacks.

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 aerial strikes on civilian areas after more than three years of war. Over the past week, Russia launched some 1,270 drones, 39 missiles and almost 1,000 powerful glide bombs at Ukraine, Ukrainian President Volodymyr Zelenskyy said Monday.
