KYIV, Ukraine—Russia and Ukraine accused each other Friday of shelling a prison in a separatist region of eastern Ukraine, an attack that reportedly killed dozens of Ukrainian prisoners of war who were captured after the fall of a southern port city in May.
Russia said Ukraine’s military used U.S.–supplied multiple rocket launchers to strike the prison in Olenivka, a settlement controlled by the Moscow-backed Donetsk People’s Republic. Separatist authorities and Russian officials said the attack killed 53 Ukrainian POWs and wounded 75.
