MOSCOW—The Kremlin said on Tuesday it did not know the location of two Americans captured while fighting in eastern Ukraine, but that they were mercenaries and could be sentenced to death in Russian-backed breakaway territories.
Americans Alexander Drueke, 39, and Andy Huynh, 27, went missing this month while fighting near Kharkiv. Russian state media later showed video interviews with the pair, saying they had been captured by Russian-backed forces.
