"Russian terrorists have once again targeted energy infrastructure. Unfortunately, there is damage in a number of regions," Shmygal said in a post on social media that also called for support from Ukraine's allies to help thwart aerial attacks.

AFP journalists in the capital heard explosions ring out early on Monday -- likely from air defence systems -- while residents rushed to take shelter in metro stations.

Authorities in at least six regions reported hearing explosions.

Sergiy Lysak, governor of the central Dnipropetrovsk region, stated that Russian forces had launched a large-scale attack. Energy facilities in the Lviv region were among those hit, Lysak added.

In the Kyiv region, drones and missiles targeted energy infrastructure, injuring one person, according to local authorities.

"As a result, there are partial power outages in Lviv and the surrounding region," said governor Maksym Kozytskyi on social media.

Earlier, an attack on an industrial facility in the eastern Poltava region injured five people, according to governor Filip Pronin.

Since its invasion in February 2022, Russia has launched dozens of large-scale drone and missile attacks on Ukraine.

Most recently, those strikes have targeted energy facilities causing millions of dollars worth of damage and disrupting lives of millions of Ukrainians.
