The militias defending Iraq from Islamic State

DOWN a dusty backstreet in the Baghdad neighbourhood of Karada this month, I met Sheikh Raad Al Kafaji, a former Iraqi army officer specialising in artillery, and a veteran fighter from the days of the Iran-Iraq war.
He is head of the al Kafaji tribe and a commander in the Kata’ib Hezbollah militia, one of the Shia militias at the forefront of the fight against Isis in Iraq.
