Displaced Iraqis who fled fighting between government forces and the Islamic State (IS) group in Anbar province line up to collect donated food at the Alexanzan camp in the Dora neighbourhood on the southern outskirts of Baghdad on May 31, 2106. Only a few hundred families have managed to slip out of Anbar's Fallujah area ahead of the assault on the city, with an estimated 50,000 civilians still trapped inside, sparking fears the militants could try to use them as human shields.
