Ukraine killed at least 40 Ukrainian POWs when it shelled a prison, Russia-backed separatists claim

At least 40 Ukrainian prisoners of war captured during the fighting for Mariupol have been killed by Ukrainian shelling, Russia-backed separatists in eastern Ukraine said.

Daniil Bezsonov, a spokesman for the Russia-backed separatists in the Donetsk region, said at least 40 Ukrainian prisoners of war were killed and 130 were injured Friday when Ukrainian shelling hit a prison in the town of Olenivka.

Russia's defense ministry said Ukraine used U.S.-made HIMARS rockets in the strike, according to the Reuters news agency. The ministry put the number of injured at 75, in addition to the 40 killed.
