KYIV (June 22): Russia launched a new barrage of missiles and drones in an overnight attack on Ukraine on Saturday, damaging energy facilities in the southeast and west of the country and injuring at least two energy workers, Ukrainian officials said.

Ukraine's air defence shot down 12 of 16 missiles and all 13 drones launched by Russia in the second large strike this week, the air force said. The air alerts in Ukrainian regions lasted for several hours in the middle of the night.

National grid operator Ukrenergo said equipment at its facilities in Zaporizhzhia region in the southeast and Lviv region in the west were damaged by the strikes.

Two energy workers in the Zaporizhzhia region were wounded and taken to the hospital, it said.

Ivan Fedorov, Zaporizhzhia's governor, said the fire broke out at an energy infrastructure facility in the region and further damage assessment was underway as repair brigades and emergency workers dealt with the attack.

"We can say for sure: the enemy will not stop. Ukraine needs air defence systems," Fedorov said on the Telegram messaging app.

Moscow has said its air strikes against the Ukrainian energy infrastructure were in retaliation for Ukrainian drone attacks on the Russian territory.

Lviv regional Governor Maksym Kozytskyi said 67 firefighters and 12 special vehicles were involved in putting out the fire in his region on Ukraine's Polish border. He said there were no casualties in the Lviv region.

Since March, Russian forces have intensified their bombardments of the Ukrainian power system, knocking out about half of the country's available generating capacity and causing a severe energy crunch.

Despite warm summer weather, Ukrainian cities face scheduled energy cutoffs and the country's electricity imports from its European neighbours are at record levels.
