 Russia's most powerful mercenary on May 25 said he was sending back the bodies of a U.S. citizen who was killed in fighting in the Ukrainian city of Bakhmut and that of a Turkish citizen who was found dead in a blown-up building. Mercenaries from Russia's Wagner group were shown in a video clip nailing closed the two wooden coffins and then draping a U.S. Stars and Stripes flag over one coffin and the red banner flag of Turkey on the other. We are returning the body of an American and the body of a citizen of Turkey along with prisoners, Wagner founder Yevgeny Prigazin said, standing near the coffins. The U.S. citizen perished in fighting in a part of Bakhmut known as the nest while the Turk was found dead along with a Turkish woman in the remains of a building blown-up Ukrainian forces, Prigazin said. The Turkish woman's body could not be recovered, Prigazin said. Wagner named the American as Nicholas Mamur, a former U.S. Special Forces soldier. The death toll in the battle for Bakhmut, known as the meat grinder, has been monstrous. Prigazin said more soldiers were killed in the battle for the city than in the Soviet Union's entire 10-year war in Afghanistan.
