A truck carrying two civilians was captured by ISIS fighters near the base of the Iraqi Army in Ninevah province, in Iraq’s Nineveh Province, on March 15, 2018.
A video posted to Twitter by the U.N. High Commissioner for Human Rights showed a man wearing a black jacket, a white mask, and carrying a rifle in the video.

The U.K.-based Syrian Observatory for Human rights, a Britain-based monitoring group, said the convoy was carrying a humanitarian aid convoy and two medical aid workers.
