One of Iraq's top Sunni political groups has agreed to support a new constitution in Saturday's referendum, after reaching a deal with negotiators to consider future changes to the draft.
Iraq's Shi'ite and Kurdish-dominated parliament is to discuss the deal at a special session later Wednesday.
Late Tuesday, Iraq's main Sunni Arab political party (the Iraqi Islamic Party) announced its support for the draft constitution, after Shi'ite and Kurdish negotiators agreed to allow Parliament to consider amendments to the constitution.
It is unclear if other Sunni groups not involved in negotiations will reverse their calls for voters to reject the constitution.
U.S. officials have also been pressing Sunnis to back the constitution in the hope it will weaken the insurgency and enable the withdrawal of foreign troops.
In Baghdad today, Iraqi police say at least six people were injured when a suicide car bomber struck a government convoy.
