Iraq's electoral commission on Monday recommended a 45-day delay in parliamentary elections until Feb. 27, raising concerns that the postponed balloting could complicate the planned withdrawal of U.S. combat troops and bring a possible surge of violence.

American commanders have noted the chance of increased pre-election bloodshed aimed at destabilizing the pro-Western government. A series of attacks struck around the country as officials tried to hammer out the election timetable, including an explosion outside a Baghdad elementary school that killed 10 people, including six children.

The recommendation for Feb. 27 voting was sent to Iraq's presidential council, which still must approve it, said Qassim al-Aboudi, a senior electoral commission official. Though other dates remained on the table, there was little reason to believe the council would raise objections.

The delay from the original Jan. 16 date is needed to give authorities time to prepare after months of political stalemate that was finally broken with a dramatic vote by lawmakers Sunday just minutes before a midnight deadline on adopting new voting rules.

"The passage of the elections law proves we have entered a new stage based on respect and dialogue, and that the language of dialogue has prevailed over the language of violence and rift," President Jalal Talabani, the Kurdish representative of the three-member presidential council, said Monday in a televised address.

At the center of the dispute were demands by Vice President Tariq al-Hashemi for a greater political voice for minority Sunni Arabs and changes in the distribution of seats in Iraq's expanded 325-seat parliament.

U.N. Secretary-General Ban Ki-moon congratulated Iraqi leaders and lawmakers for overcoming their differences to reach a compromise, new U.N. spokesman Martin Nesirky said.

"The secretary-general firmly believes that these elections will be an important step forward for Iraq's political and democratic progress," Nesirky said at U.N. headquarters in New York.

Ban reaffirmed the U.N.'s commitment to provide technical assistance and support to Iran's Independent High Electoral Commission, he said.

The secretary-general "encourages the Iraqi people and all political parties to participate in a process that will shape their country's future and contribute to national reconciliation," he said.

Ban reaffirmed the U.N.'s commitment to provide technical assistance and support to the electoral commission, Nesirky added.

There were concerns the delay could throw snags into withdrawal plans for the U.S. military, which is keeping the bulk of its 120,000 troops in place until the election.
