ISIS claimed responsibility for the assassination on Monday of a candidate in Iraqs parliamentary election on the eve of the May 12 polls. Faruq Zarzur al-Juburi, a candidate loyal to Vice President Ayad Allawi, was shot dead by gunmen at his home near Mosul, a local official said. Local official Salah al-Juburi said the gunmen killed the candidate at his home in the town of Qayyarah, 70 kilometers south of Mosul, after storming his house. ISIS had threatened to attack Iraqi polling stations and voters during the parliamentary election that will be held on Saturday. The May 12 polls are the first to be held since Iraqi Prime Minister Haider al-Abadi declared victory over the militants in December.
