Russian drones targeted the capital Kyiv and other cities in the early hours of today, hitting critical infrastructure in Lviv in the west, according to Ukrainian officials.
Ukraine’s air force says 35 drones were launched and all but three were shot down.
According to local authorities, the attack on Lviv triggered a fire, but no-one was injured.
The raid on Kyiv and a missile attack on Zaporizhzhia in the south were both described as massive.
More than 20 drones were fired at Kyiv in waves from Russian territory to the north and from the coast of the internal Sea of Azov in the south-east, according to the air force.
It was the first such incident in 18 days.
In southern Ukraine, Zaporizhzhia was attacked by a number ballistic missiles, according to local officials but they added that no one had been hurt.
Three drones were also shot down over the southern region of Mykolaiv.
The Zaporizhzhia region is the focus of much of the Ukrainian military’s current offensive to recapture territory seized by Russia at the start of its full-scale invasion in February 2022
