The UN Human Rights Monitoring Mission in Ukraine reported that at least 328 civilians were killed and 2,105 injured in September. The total number of casualties was 85% higher than in September 2025.
The data comes from a monthly report on the protection of civilians that the UN mission published. According to Bloomberg, the report was presented on Friday, 16 October. The mission’s website is dated 15 October. This is the highest September figure since the full-scale invasion began in 2022. A year earlier, in September 2025, the mission counted 249 killed and 1,068 injured.
How Civilians Were Killed
The main cause of casualties remained long-range weapons, namely missiles and drones. They accounted for 53% of all civilian casualties: 165 killed and 1,119 injured. In second place were short-range drones: 87 killed and 475 injured, or 23% of casualties.
Casualties were recorded in 22 regions of Ukraine and in Kyiv. The capital had the most: 32 killed and 340 injured. The mission says that in Kyiv, civilians were killed or injured on 22 of the 30 days of September. No earlier month since the full-scale invasion began has seen such frequency. Chernihiv was not affected here; instead, Kherson (16 killed, 202 injured), Sumy (11 and 131) and Zaporizhzhia (7 and 127) were also hard hit.
The verified data also includes 18 killed and 44 injured in territories occupied by Russia. The mission notes separately that, according to public statements by Russian authorities about individual incidents in September, at least 87 people were killed and 436 injured in the occupied areas. In Russia itself, at least 53 people were reportedly killed and 462 injured. The UN has not verified these figures.
Trend Since the Start of the Year
From January to September 2026, at least 2,570 civilians were killed and 15,211 injured. According to the mission, this is 59% more than in the same period of 2025 and more than twice as many as in 2024.
September had fewer casualties than the previous months of this summer. According to the mission’s earlier reports, at least 372 civilians were killed and 2,349 injured in August. July was the deadliest month of 2026. The first version of the report gave 437 killed and 2,610 injured, and the figures were later corrected to 448 and 2,675. At the time, the mission wrote that the number of deaths was the highest since May 2022. The comparison with September 2025 therefore rests on a lower base, not on the worst month of the year.
How the UN Counts
The mission reports verified figures and stresses that they are a lower bound: the actual scale is probably higher. The 85% figure refers to the total of killed and injured (2,433 versus 1,317 a year earlier). The number of killed rose less, by about one third (328 versus 249).
What It Means
For Poland, the data confirm that Russian missile and drone attacks on Ukrainian cities are intensifying, including on Kyiv. This adds pressure for further deliveries of air defence systems from allies, as well as affecting the number of people seeking shelter abroad. As of publication, it has not been reported whether the report will prompt a reaction from Kyiv or Moscow.
