Masked Sunni Muslims gunmen take up position with their weapons during clashes with Iraqi security forces outside the city of Falluja, 70 km (44 miles) west of Baghdad, February 23, 2014. Members of the extremist Islamic State in Iraq and the Levant are holed up inside Fallujah along with Sunni fighters angry at Prime Minister Nouri Maliki over what they say are policies which discriminate against Iraq’s Sunni minority. The Iraqi government declared a ceasefire over the weekend but clashes flared periodically on Sunday, according to residents in Fallujah. The United Nations estimates that more than 370,000 people have been uprooted from their homes due to the fighting in Anbar. Picture taken February 23, 2014.
