Kurdish troops liberate the Islamic State held town of Sinjar, home to thousands of Yazdids who were displaced or enslaved last August after much of northern Iraq was seized by the group. A fighter from the Kurdistan Workers Party, or PKK, which has been designated a terrorist group by the US and Turkey, celebrates his group's part of liberating the city on November 13, 2015.
