Iraq has called on the U.S. to arm 100,000 Sunni tribesmen in the country against the Islamic State of Iraq and al-Sham, according to an adviser to Iraqi parliament speaker.Wahdah al-Jamili's comments came Friday following a meeting between U.S. Senator John McCain, and Iraqi parliament Speaker Salim al-Juburi in the Iraqi capital, Baghdad."Juburi has called on the U.S. to provide arms to 100,000 Sunni tribesmen living in four regions that are controlled by the ISIS," Jamili told The Anadolu Agency.He said that some tribesmen and members of parliament also attended the meeting.Juburi and McCain discussed the political and security situation in Iraq, as well as the problems in northern and western provinces that were partially controlled by the militant group, according to the adviser. "They talked about the issue of increasing efforts of the U.S.-led coalition to overcome difficulties in Anbar, Saladin, Nineveh and Kirkuk," Jamili said.The issue of increasing training and weapons aid to Iraqi security forces was also discussed, he added.Armed tribesmen, who have been fighting against the ISIS along with security forces, recently called on the Iraqi government to provide them with arms and ammunition as they were running out of weapons and military supplies; but said that the government didn't meet their demands.Iraq has been in a security vacuum since June, when ISIS overran Mosul and declared what it calls a caliphate in parts of Iraq and Syria.The U.S. is leading an international coalition that has carried out numerous airstrikes against ISIS in Iraq and Syria.
