Camp trains children to fight IS

Hundreds of boys mobilized after top Shiite cleric's edict

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 preteenagers to use their summer vacations to prepare to fight the Sunni extremists.
