Yassir Bashar, 35, is a Yazidi from Shengal, Iraq boarding a bus from Idomeni camp to Petra, a camp exclusively for Yazidis. When ISIS swept through his village, they captured his wife Khaida and killed one of his two sons, along with two of Yassir's brothers. After a year in captivity, his younger son, Sezar, 5, was released and brought to Germany with his sister and her husband. Yassir arrived in Greece last month to find the border closed. He has heard only once from his wife, who is imprisoned in Raqqa, Syria. She wrote him a letter that was carried to him by a hostage released by ISIS. He is trying desperately to reunite with his son and sister in Germany.
