A member of the Iraqi forces walks past a mural bearing the logo of the Islamic State (IS) group in a tunnel that was reportedly used as a training centre by the jihadists, on March 1, 2017, in the village of Albu Sayf, on the southern outskirts of Mosul. Iraqi forces launched a major push on February 19 to recapture the west of Mosul from the Islamic State jihadist group, retaking the airport and then advancing north.
