Young fighters

Iraqi militias train young teens to face the threat of IS

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.

These young fighters could have serious implications for the U.S.-led coalition, which provides billions of dollars in military and economic aid to the Iraqi government.
