Ukrainian officials have accused Russian forces of executing nine captured troops in the Kursk border region, denouncing Moscow for violating "all the rules and customs of war," while Kyiv said at least two people were killed and 22 others injured in Russian attacks in Ukraine over the past 24 hours.
Dmytro Lubinets, Ukraine's commissioner for human rights, said he had written to the United Nations and the Red Cross concerning the allegations, which officials said are the result of Ukrainian battlefield analysis site DeepState, which published drone footage purporting to show the dead troops.

Russia has not commented on the reports, which could not immediately be verified.
The allegations are the latest in a long list of reports by Kyiv outlining incidents of alleged executions of Ukrainian prisoners by Russian forces.
Kyiv said it has documented evidence related to the execution of a total of 93 Ukrainian prisoners of war, according to a law enforcement official tasked with investigating war crimes related to Russia's full-scale invasion of Ukraine.
Yuriy Belousov, who heads the Prosecutor-General's Office department in charge of investigating crimes committed in armed conflict, provided the figure during a live television appearance on October 4.
Cases of the alleged execution of Ukrainian prisoners of war fall under the mandate of the International Criminal Court (ICC), and the court is entitled to try such cases, ICC Chief Prosecutor Karim Khan said on October 9, without referring to specific cases.
"Each of the provisions of the Rome Statute [the founding treaty of the ICC]...can be applied. They all matter. Our duty is to apply a methodological approach and put together an investigation strategy," Khan told a roundtable at The Hague attended by journalists from Schemes, the investigative unit of RFE/RL's Ukrainian Service.
In the latest incident, images published by DeepState showed the apparently dead Ukrainian troops stripped to their underwear and lying face down in the Kursk region following a rapid offensive by Russian forces.
"These actions must not go unpunished, and the enemy must bear full responsibility," Lubinets wrote in a post on Telegram. "Russia is a terrorist country that violates all the rules and customs of war."
The accuracy of the videos could not independently be verified.
The accusations come amid reports that at least two people were killed and 22 others were injured in Russian attacks over the past 24 hours in Ukraine.

Russia launched 68 drones and four missiles on Ukrainian territory overnight, according to the latest update by Ukraine's air force.
