Civilians caught in west Mosul crossfire

Civilians from western Mosul are blaming aerial attacks for causing the most casualties in the offensive.

More than half a million people are trapped in the ISIL-held west of the city, which Iraqi forces are trying to recapture.

Some of the residents who have managed to flee say they had been living under constant bombardment.
