One of Iraq's biggest Sunni parties has said it might back the country's constitution, despite calling for changes to a text agreed by the Shia-dominated parliament. The Iraqi Islamic Party, a multi-ethnic group seen as moderate Islamist and opposed to violence, said on Monday that there was still room for negotiation on the constitution. "We have not signed the constitution and we still have the time starting from now until the referendum comes. [But] we might say yes to the constitution if the disputed points are resolved," party general-secretary Tariq al-Hashmi told a news conference. The text read to parliament failed to overcome objections by Sunnis, who lost their political dominance with the fall of Saddam Hussein, despite US efforts to broker a compromise between Iraq's divided ethnic and religious groups.
