Chairman Humam Hammoudi told parliament that he had recommended the commission formally ask the National Assembly for more time after the members deadlocked on such issues as the role of Islam, federalism and distribution of the national wealth.
But U.S. authorities ratcheted up pressure Sunday to stick by the deadline, which Washington considers essential to maintain political momentum, undermine the insurgency and pave the way for the Americans and their coalition partners to draw down troops next year.
After meeting with U.S. Ambassador Zalmay Khalilzad, President Jalal Talabani said Sunday that all efforts must be made to stick by the timetable and finish the charter by Aug. 15. Intense meetings took place late into the night to find a way out of the impasse.
In other developments:
The deadline for the constitutional commission to ask for an extension was Monday. Appearing before parliament Monday, Hammoudi said that if political leaders meet this week to resolve the differences, "on Aug. 15 we can be able to conclude the constitution."
Hammoudi added one condition: "that the leaders of the bloc meet on Aug. 5, and on Aug. 12, we receive the results of their discussion. If there are any points of disagreement among the leaders, they will be brought forward to the National Assembly in order for them to solve it."
