September was the deadliest month for Russia’s army since the start of the war in Ukraine, British military intelligence said on Monday.

The average casualty rate for the Russian army rose to 1,271 soldiers killed or badly injured per day.

Previously, the highest daily casualty rate for Russian soldiers had been in May, with an average of 1,262 soldiers killed or injured.

“The increase in the casualty rate since May 2024 is almost certainly due to the extension of the combat zone to include both Kharkiv and Kursk military operations, and increased intensity along the frontline,” the Ministry of Defence said.
