The UN Human Rights Office verified some 15,280 civilian casualties in Ukraine during the first eight months of 2026, 55% more than in the same period last year, UN High Commissioner for Human Rights Volker Türk said on 2 October.

Türk's statement comes as Russia has begun its Winter 2026-2027 campaign of long-range strikes against Ukrainian energy infrastructure. The Institute for the Study of War (ISW) said Russian forces began the campaign in late September. Damage to energy infrastructure disrupt electricity, heating, and water supplies during the winter, increasing the risks to civilians.

Russian glide bombs killed and injured nearly 2,500 civilians in Donetsk, Kharkiv, Sumy, and Zaporizhzhia oblasts during the first eight months of the year, 62% more than in the same period last year, according to UN figures.

"As winter approaches, Ukrainians fear the worst is yet to come," Türk said.

On 4 October, Russia's Defense Ministry announced that it was intensifying strikes on infrastructure in Kyiv City and Oblast and across Ukraine, according to ISW.

Why Russia is turning to long-range strikes

ISW said Ukraine's 2026 battlefield successes "appear to be forcing" Russian President Vladimir Putin to shift focus from advances on the battlefield toward a winter campaign intended to compel Ukraine to surrender.

A week earlier, ISW assessed that Putin was likely attempting to force Ukraine to capitulate before spring 2027, with his theory of victory heavily relying on cheap, jet-powered Geran-type drones.

A toll rising all year

The 15,280 figure extends a trend the UN has tracked all year. Over the first seven months of 2026, its monitoring mission verified 1,839 civilians killed and 10,638 injured. In September, UN Under-Secretary-General Rosemary DiCarlo told the Security Council that more civilians were killed or injured in the first eight months of 2026 than in all of 2025.
