Russian strikes have killed or wounded more Ukrainian civilians in the first eight months of 2026 than in all of last year, a senior United Nations official told the Security Council, Censor.net reported. The official warned that the toll keeps climbing as missiles and drones increasingly reach cities far from the front line. She also cautioned that mounting attacks on Ukraine's battered energy grid could push millions into a dark, cold winter.

In the war's fifth year, Russia's long-range strikes on Ukrainian cities have shifted the danger from the front to the streets where people live, and the rising civilian toll now tracks how far those weapons reach.

Casualties outpace all of 2025

Rosemary DiCarlo, the UN Under-Secretary-General for Political and Peacebuilding Affairs, gave the toll as the Council met on Ukraine, Ukrinform reported.

"In just the first eight months, more civilians were killed or injured in Ukraine than in all of 2025," she said.

The heavy toll already recorded in September shows the trend continuing, she added, as strikes hit populated areas away from the front.

The UN human rights office has confirmed at least 17,257 civilians killed since February 2022, including 835 children. Another 53,693 people have been wounded, among them 3,247 children, and DiCarlo said the real numbers are likely far higher. Kyiv and other cities have faced near-daily attacks in recent weeks, she said, with strikes hitting railways, shopping centers, gas stations, warehouses, and food and logistics firms.

A warning over the coming winter

DiCarlo said the mounting strikes on Ukraine's already-damaged energy infrastructure are especially worrying with another war winter near.

"The cumulative impact of these strikes could plunge millions of people into darkness and cold in the coming months," she said.

She urged an immediate moratorium on strikes on populated areas and urgent action to protect the power grid. Targeting civilians and civilian sites is prohibited under international law, she noted.

The warning follows the deadliest stretch of the war for civilians, when UN monitors counted 437 people killed in July, the worst monthly toll since May 2022. Russia has also renewed strikes on gas production and power plants ahead of the heating season.

Russia's memorandum on a peace proposal is the "best offer Ukraine can get today," Russia's envoy to the United Nations (UN), Vasily Nebenzya, said at a UN Security Council meeting on June 20.

"During the direct Russian-Ukrainian talks that were held, we presented our memorandum on a peaceful settlement. It consists of two parts: conditions for a comprehensive long-term peace and conditions for a ceasefire," Nebenzya said.

"This is the best offer Ukraine can get today. We advise accepting it as things will only get worse for Kyiv, from here on out," he said.

At Istanbul peace talks on June 2, Russian negotiators told the Ukrainian delegation that their so-called "peace memorandum" is an ultimatum Kyiv cannot accept, President Volodymyr Zelensky said in an interview published on June 10.

"They even told our delegation: we know that our memorandum is an ultimatum, and you will not accept it," Zelensky said. "Thus, the question is not the quality of the Istanbul format, but what to do about the Russians' lies."

"In Istanbul, we also agreed on a large-scale exchange of prisoners of war," Nebenzya said at the UN Security Council meeting on Ukraine.

Aside from agreeing on large-scale prisoner exchanges, peace negotiations between Ukraine and Russia have been largely inconclusive as Moscow continues to issue maximalist demands toward Kyiv.

Nebenzya noted that Ukraine and Russia should resume direct peace talks in Turkey after June 22, despite Russia's intensified drone and missile attacks on Ukraine.

On June 17, a Russian drone and missile attack on Kyiv killed 30 people and injured another 172. The nearly nine-hour-long strike saw Moscow's forces launch large numbers of drones and missiles at Ukraine's capital.

Russia's statements diverged from those of other speakers at the UN Security Council meeting on June 20.

"We call on Russia to agree to an unconditional ceasefire. Russia initiated this war; we call on Russia to end it," Barbara Woodward, the U.K.'s Permanent Representative to the UN, said.

Russia has illegally laid claim to five Ukrainian regions despite not controlling all of the territory. The regions include Donetsk, Luhansk, Zaporizhzhia, and Kherson oblasts, as well as the Autonomous Republic of Crimea.
