Volunteers, who have joined the Iraqi army to fight against predominantly Sunni militants from the radical Islamic State of Iraq and the Levant (ISIL), sit as they wait together in Baghdad June 15, 2014. The insurgent offensive that has threatened to dismember Iraq spread to the northwest of the country on Sunday, when Sunni militants launched a dawn raid on a town close to the Syrian border, clashing with police and government forces. ISIL fighters and other Sunni Muslim armed groups have stormed several towns on the road to Baghdad after seizing Mosul nearly a week ago - an offensive which only stalled as it approached the mainly Shi'ite capital.
