Meanwhile, the Minister of State for National Reconciliation, Amer Khuzaie, announced the launch of the first phase of reconciliation with the armed groups, stressing that this will be followed by other stages.
"The national reconciliation is only with armed groups who carried weapons against the occupiers and not against Iraqi people," Khuzaie said in a joint news conference with leaders of armed groups.
Khuzaie refused to give list of names of the armed groups who attended the conference, but he said at least four armed groups agreed to join this conference and to support the political process in Iraq.
"Those armed groups realized that (the) Iraqi government is determined to end the foreign troops presence in Iraq through political agreements," Khuzaie added.
