The families of Alexander Drueke, 39, and Andy Huynh, 27 said last week that the pair, both US military veterans and residents of Alabama, had disappeared in Ukraine. Family members said they had last been heard from on June 8 in the Kharkiv region.
Fellow fighters have said that both men were captured during clashes with Russian forces on June 9. If confirmed, they would be the first Americans captured in the conflict. However, Washington and Moscow have offered few specifics in recent days.
