A suicide bomber dressed as a veiled woman killed 14 people and wounded 13 others in a displacement camp west of the Iraqi capital Baghdad on Sunday, Reuters has reported.
Daesh militants, who have been facing mounting US-backed offensives in Iraq and neighbouring Syria, claimed responsibility for the assault, Reuters added.
The camp, known as "kilo 60", houses people forced out of Sunni Muslim areas control by Daesh in the Euphrates river valley, the sources said.
According to Reuters, the militants said in a statement they had been targeting an Iraqi army position.
The hardline Sunni group has all but lost its capital in Iraq, Mosul, while its capital in Syria, Raqqa, is isolated from the rest of the territory under its control across the border.
