WASHINGTON – Three Ukrainians were killed, at least eight wounded and thousands more experienced blackouts Friday after Russia launched its largest assault this year on power facilities in the war-torn country.

Ukrainian President Volodymyr Zelensky announced Moscow had sent more than 60 drones and fired roughly 90 rockets in an complex attack on the country’s electrical grid.

The assault came as Kyiv struggles with a lack of air defense weapons and systems, a shortage which has only grown more acute as House Speaker Mike Johnson (R-La.) refuses to call up a Senate-passed supplemental funding bill that would include $60 billion in assistance for Ukraine.

“With Russian missiles, there are no delays, like [there are] with aid packages to our state,” Zelensky said in an apparent swipe at Washington. “Shahed [drones] don’t have indecisiveness, as do some politicians.”

“It is important to understand the cost of delays and postponed decisions,” he added.

Friday’s assault also caused a fire at a hydroelectric station in Dnipro that supplies electricity for Zaporizhzhia Nuclear Power Plant, which has been under occupation by Russian forces since the war’s first weeks.

While the fire briefly left Europe’s largest nuclear plan without its main external power line, Ukraine’s nuclear energy operator said the juice was restored several hours later, International Atomic Energy Agency head Rafael Grossi told the Associated Press. 

Since the war’s start, Moscow has targeted Ukrainian energy sources, often with cruel consequences for civilians – such as blackouts during the country’s bitter-cold winters.

“Even last winter, attacks on our energy system were not as large as they were this night,” Volodymyr Kudrytskyi, the head of energy utility Ukrenergo told the Associated Press.

Blackouts also can temporarily shut down Ukraine’s air raid alarm systems that warn civilians of incoming attacks, Ukrainian officials told The Post, increasing the risk of civilian deaths.

That happened Friday in Kharkiv, when Russian strikes on multiple energy facilities in the region caused blackouts in Ukraine’s second-largest city.

To make do, Regional Gov. Oleh Syniehubov told AP that police would inform residents of possible air raids through loudspeakers and walkie-talkies. Additionally, Ukraine’s highly accurate air alert phone cell phone app would remain in service.

Additional attacks took place in western Ukraine, killing two in the Khmelnytskyi region about 200 miles west of Kyiv. Western Ukraine typically sees fewer attacks due to its distance from the eastern front, where the major fighting is taking place.

Power outages also left 1,060 miners trapped in Dnipropetrovsk Oblast, but an evacuation was underway, private energy company DTEK told the Associated Press.
