Russia’s attacks came on the coldest day of the Ukrainian winter so far, with temperatures around -6C.

Along with the damage caused in the Ivano-Frankivsk region, energy and infrastructure facilities were damaged in the Lviv and Ternopil regions.

No critical or residential infrastructure was hit in the Kyiv region, according to Ruslan Kravchenko, the area’s governor.

Five out of the country’s nine operating nuclear reactor units have been operating with reduced power.

As a result of the attack, the Ukrenergo National Power Company had to increase power supply restrictions on Friday, with rolling blackouts being introduced in all regions.

Ukrenergo added that during the day on Friday, electricity would be imported from Poland, Romania, Slovakia, Hungary and Moldova.

Russia launched a full-scale invasion of Ukraine in February 2022.

In total, Russia has captured and retaken about 2,350 sq km of territory (907 sq miles) in eastern Ukraine and in Russia’s western Kursk region.
