KYIV - Ukraine's air defences downed 41 of 80 Russian drones launched overnight, the Ukrainian military said on Sunday.
The air force said it lost track of 32 drones but gave no further details.
The military and local authorities reported no casualties from the attacks or damage to critical infrastructure.
"Russia does not stop in its terror against Ukraine. Daily aggression against our people, our towns and villages. Strikes with various types of weapons," Ukrainian President Volodymyr Zelenskiy said on the Telegram messenger.
He said that Russia had used more than 1,100 guided aerial bombs, more than 560 attack drones and about 20 missiles over the past week against Ukraine.
