GENEVA (Reuters) - The U.N. human rights chief on Tuesday called for accountability for the deaths of at least 50 Ukrainian prisoners of war last year in an explosion in a Donetsk region detention facility, rejecting Moscow's claim that they were killed by a rocket.

The prisoners being held in a Russian-controlled detention facility in Olenivka, in the eastern Donetsk region, were killed by an apparent explosion July 28-29 2022. Unverified Russia media video footage showed the burned out remains of the prison and charred bodies.
