Putin drew attention to the fact that in the pre-trial detention center in Yelenovka, as a result of a missile attack by the Armed Forces of Ukraine, a large number of Ukrainian prisoners of war held there died.

Earlier, UN Secretary-General António Guterres said that an officer from Brazil, Carlos dos Santos Cruz, would lead a mission to investigate the shelling of a pre-trial detention center in Yelenovka in the Donetsk People's Republic.

The Russian Ministry of Defense reported that the Armed Forces of Ukraine fired at the detention center in Yelenovka with captured Ukrainian soldiers and militants located there using the American HIMARS multiple launch rocket system.
