Faysh Khabur, Iraq (CNN) -- In an exodus of almost biblical proportions, thousands trudge across a river to escape killers belonging to the Islamic State in Iraq and Syria, or ISIS.
Entire families carry nothing but the clothes on their backs. Some are barefoot.
Jamal Jamir, a 23-year-old university student from Sinjar, told CNN his family fled to the barren and windswept Mount Sinjar more than a week ago after ISIS captured their town. The group, which calls itself the Islamic State, has been on a rampage, killing members of various minorities, including Yazidis.
Jamir said after ISIS arrived in his town, Arab neighbors of his turned on the minorities and helped ISIS kill. "They join them, and actually they kill us."
