Russia targeted essential infrastructure in western Ukraine, according to officials on Wednesday, marking the latest airstrike on the country’s already strained energy grid as winter approaches. The governor of the Lviv region reported that two facilities in the Drohobych and Stryi districts sustained damage from the assault. In the nearby Ivano-Frankivsk region, the governor noted that local air defenses successfully intercepted Russian attacks on facilities there.

Both officials confirmed that no injuries were reported, although further details were not disclosed. Earlier in the day, Ukraine’s national grid operator implemented emergency power outages across six regions, following alerts from Kyiv’s air force regarding missile launches by Russia during a nationwide air raid warning. Additionally, Ukrainian Energy Minister German Galushchenko announced on social media that “preventative measures” concerning the distribution system were also being implemented.

Russia has consistently conducted airstrikes on Ukraine’s energy infrastructure as its ground forces continue their offensive in the ongoing invasion that has persisted for three years.
