Islamic State fighters have killed several civilians over collaboration with security troops, southwest of Kirkuk, a security source in the province. “The so-called head of the legislative court in al-Hawija district (55 KM southwest of Kirkuk) ordered hanging some civilians, who were detained by the militants few days ago over spying for the troops”, an anonymous source told BasNews on Thursday without giving details on the number of the victims. “The execution took place today at one of IS camps near Hawija”, the source said, adding that the bodies of the victims were not handed to their relatives. Hawija is a strategic town which has fallen into the hands of IS since mid-2014. Iraqi authorities postponed an operation to liberate the town last year, instead they moved onto central Mosul. The Iraqi government is expected to launch an offensive to retake IS-occupied areas in Kirkuk once it is done with eradicating IS from Mosul, the group’s biggest bastion in Iraq.
