(AP) – In the steamy Baghdad night, sweat poured down the faces of the Iraqi teens as they marched around a school courtyard, training for battle against the Islamic State group. This is summer camp in Iraq, set up by the country’s largest paramilitary force after Iraq’s top Shiite cleric issued an edict calling on students as young as middle-school age to use their summer vacations to prepare to fight the Sunni extremists. Dressed in military fatigues, 15-year-old Asam Riad was among the dozens of youths doing high-knee marches, his chest puffed out to try to appear as tall as the older cadets.
