Dozens of people, including a United States citizen, have been released in the latest prisoner swap between Russia and Ukraine, nearly 10 months into a grinding war that began after Moscow invaded its neighbour. The latest exchange included 64 Ukrainian soldiers and a US national living in Ukraine, Andriy Yermak, the head of President Volodymyr Zelenskyy's office said on Wednesday. Yermak identified the American as Suedi Murekezi who he said had been "helping our people" before he ended up in Russian custody. The White House national security spokesman, John Kirby, did not name the freed American, citing privacy concerns. "We certainly welcome that news," Kirby told reporters.
