Nearly two days after a suicide truck bomb ripped through Baghdad, families are still hoping that rescuers searching through the rubble can locate the bodies of their loved ones.

Iraqi troops have retaken the city of Ramadi from ISIS, the country's military said.

Car bombs and suicide attacks targeting mainly Shi'ite Muslim districts of Baghdad killed 35 people on Sunday, one of the heaviest recent tolls in the Iraqi capital, which has faced a wave of bombings by Islamic State militants.

Turkey is moving to reverse its non-intervention stance and approve the use of force in Syria and Iraq to fight radical Islamic State militants who have advanced against cities along the Syrian-Turkish border.

The Obama administration's decision to release secret details of an unsuccessful mission in Syria last month to rescue several Americans held captive by extremists is raising concerns that the disclosure could make it harder for the military to carry out similar operations in the future.
