Europe's biggest cities will donate power generators and transformers to help Ukrainians get through the harsh winter ahead, as part of a drive launched on Wednesday.
Since October, Russia has been targeting Ukraine's civil power and heating systems with long-range missiles and drones. Moscow says the aim is to reduce Kyiv's ability to fight and push it to negotiate.
"Ten million Ukrainians are currently without electricity as a result of Russia's attacks on critical civilian infrastructure," European Parliament President Roberta Metsola told a news conference on the "Generators of Hope" campaign.
