Iraqi Prime Minister Haider al-Abadi said recently that any group taking up arms in Iraq outside the state's official framework will be considered outlaws. However, it seems at least some of the factions fighting under the banner of the Popular Mobilization Units (PMU) in Iraq would not obey Abadi's order.

On March 22, Abadi spoke at a meeting of the Global Coalition to Counter ISIS (Islamic State, or IS) in Washington. Also during his trip, he told the media that IS will be eliminated from Iraq's cities "within weeks."

What will happen then? Hashim al-Musawi, the spokesman for Iran-controlled, Shiite Iraq militia known as the Islamic Resistance Movement in Iraq (al-Nojaba), announced earlier in the month the formation of the Golan Liberation Brigade. But the announcement appeared to be more a declaration that Iran-affiliated Iraqi militias will be ready to take on a greater role in the region once IS is gone. (In addition, Musawi threatened to take military action against Turkish forces stationed near Mosul if they refuse to leave Iraq.)

The brigade announcement carried great symbolism, as the press conference was held in the office of the Iranian news agency Tasnim, which supports the Islamic Revolutionary Guard Corps (IRGC) in Tehran.
