A member of the Iraqi forces walks past a mural bearing the logo of the Islamic State group in a tunnel that was reportedly used as a training center by the jihadists, on March 1, 2017, in the village of Albu Sayf, on the southern outskirts of Mosul.

A decade ago, the self-proclaimed Islamic State group held vast swaths of territory across Iraq and Syria, but President Trump declared it destroyed in 2019.
