Ukraine and Russia have begun the exchange of 1,000 prisoners of war, the largest such swap since the beginning of Russia's full-scale invasion of Ukraine in February 2022.
Two U.S. military veterans who disappeared three months ago while fighting Russia with Ukrainian forces were among 10 prisoners released by Russian-backed separatists as part of a prisoner exchange.
Mark Frerichs, a Navy veteran turned civilian contractor, was abducted in January 2020. His release centered on a prisoner exchange involving Bashir Noorzai, a notorious drug lord and Taliban member.
