Iraq: Refugees fearful of Iraq militants
Iraq says it has launched air strikes against Islamist militants advancing on the capital Baghdad.
They are targeting the ISIS fighters linked to al-Qaeda who are already in control of the major cities, Mosul and Tikrit.
The Sunni militants are now within about 80 miles of the capital after taking Iraq's second city of Mosul on Monday.
The Kurdish military has moved in to take control of the oil-rich province of Kirkuk after the national army fled.
The BBC's Paul Wood met refugees who have fled to the Kurdish countryside from Mosul.
