BAGHDAD (REUTERS, AFP) - 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 (July 2), security sources said.

Islamic State in Iraq and Syria (ISIS) militants, who have been facing mounting US-backed offensives in Iraq and neighbouring Syria, claimed responsibility for the assault.

The camp known as "kilo 60" houses people forced out of Sunni Muslim areas control by ISIS in the Euphrates river valley, the sources said. 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.

A doctor and a major both said that most of the victims were women and children, but the officer also told AFP that two security personnel including a captain were among the dead.

Adnan Fayhan, the head of the local council in the Al-Wafaa area, where the camp is located, said that there were 110 people residing in it when the attack occurred.

"All the displaced people in the camp will be brought to the 18 Kilo camp west of Ramadi," as it is "safer and receives more aid," Fayhan said.

"The 60 Kilo camp will be closed after all the displaced people have been brought to the 18 Kilo camp," he said.

There was no immediate claim of responsibility for the attack, but the Islamic State of Iraq and Syria(ISIS) jihadist group frequently carries out suicide bombings targeting civilians in Iraq.

Iraqi forces retook the cities of Ramadi and Fallujah from ISIS, but the jihadists still hold areas in western Anbar, and the province still faces major security challenges.

ISIS overran large areas north and west of Baghdad in 2014, but Iraqi forces backed by US-led air strikes and other support have since regained much of the territory they lost.
