Thousands of Sunni Arabs and secular Shi'ites marched in the Iraqi capital Tuesday to protest alleged fraud in the recent parliamentary elections.
Protest organizers called for a re-vote in parts of Iraq and said an international probe should be opened into hundreds of ballot complaints.
Initial vote results show that Shi'ite candidates won 130 seats in the 275-seat parliament. Final results are expected next month.
In the northern city of Irbil, a key Shi'ite leader, Abdul Aziz al-Hakim, met Kurdish leaders to discuss plans for forming a coalition government.
Officials said Mr. al-Hakim also was to hold negotiations with Sunni Arab leaders this week.
Meanwhile, authorities in Karbala said they had discovered a grave believed to contain the bodies of at least 20 victims from a 1991 crackdown on Iraqi Shi'ites.
