Baghdad, Iraq ? Iraqi leaders failed to meet a key deadline Monday to finish a new constitution, stalling over the same fundamental issues of power-sharing – including federalism, oil wealth and Islam’s impact on women – that have bedeviled the country since Saddam Hussein’s ouster.

Just 20 minutes before midnight, parliament voted to give negotiators another seven days, until Aug. 22, to try to draft the charter. The delay was a strong rebuff of the Bush administration’s insistence that the deadline be met, even if some issues were unresolved, to maintain political momentum and blunt Iraq’s deadly insurgency.

“We should not be hasty regarding the issues and the constitution should not be born crippled,” said Prime Minister Ibrahim al-Jaafari, a Shiite, after the parliament session, which lasted a bare 15 minutes. “We are keen to have an early constitution, but the constitution should be completed in all of its items.”

Al-Jaafari’s statement came after an apparent deal late Monday on all but two key issues fell apart, according to several Shiite politicians.

The Shiites said the unresolved issues were women’s rights, which is inextricably tied to Islam’s role, and the right of Kurds to eventually secede from the country. But al-Jaafari said the key stumbling blocks were distribution of oil wealth and federalism, another, broader way of stating the Kurdish autonomy issue.

The confusion over outstanding issues – as well as negotiators’ seeming inability to agree even on what they disagreed on – left unclear whether they will now reopen talks on all issues or just focus on a few.

Iraq's National Assembly votes unanimously for a seven day extension for the constitution draft on the eve of the original deadline Monday in Baghdad, Iraq. Iraq's parliament agreed to a seven-day extension for leaders to complete the draft constitution, after politicians failed to meet a midnight Monday deadline for agreement on the charter.

U.S. officials downplayed the significance of the delay, and President Bush expressed confidence the Iraqis would reach consensus.

“I applaud the heroic efforts of Iraqi negotiators and appreciate their work to resolve remaining issues through continued negotiation and dialogue,” he said in a statement. “Their efforts are a tribute to democracy and an example that difficult problems can be solved peacefully through debate, negotiation and compromise.”

The United States hopes progress on the political front, including adoption of a democratic constitution, will help deflate the Sunni Arab-led rebellion and enable the Americans and their partners to begin withdrawing troops next year.

Even if negotiators produce a constitution in the next week, the wide divide over issues such as federalism, oil revenues and Islam’s role are unlikely to dissipate. The majority Shiites also have a stake in federalism, hoping to create an autonomous region in the south as Kurds have in the north – both areas rich in oil. Minority Sunni Arabs oppose federalism, while showing some willingness to compromise.
