Ukrainian energy facilities have come under a massive attack from Russia, in the latest onslaught targeting the country’s power grid, officials say.

It is the eighth time Russia has launched an attack on energy infrastructure facilities in the past three months, Ukraine’s energy ministry said.

Air defence systems shot down 12 of 16 missiles and all 13 drones launched by Russia at several regions through the night, the Ukrainian air force said.

Later on Saturday officials in Kharkiv in north-eastern Ukraine said three people were killed and at least 18 injured by Russian guided bombs, with at least four explosions heard in the city.

This is one more terrorist attack, a precise attack on civilian infrastructure. There is nothing of military interest in this district," Kharkiv’s regional governor, Oleh Syniehubov said.
