The Russians are holding an American teacher hostage in Ukraine, and his mother is appealing for his release. Twenty-eight-year-old Tyler Jacob from Winona, Minnesota, was taken prisoner as he tried to flee the war-torn country. It’s not known where Jacob is being held. His mother, Tina Hauser, says she last spoke to her son early Saturday morning. Another American, 67-year-old psychologist James Hill of Idaho, has been confirmed killed. The professor had been teaching at a college in Kyiv.
