Insurgents in Iraq carried out a series of attacks Sunday, killing two American soldiers and at least five Iraqis.

U.S. officials said the two Americans were killed by bombs in the Iraqi capital.

South of Baghdad, a mortar attack killed two Iraqis, and gunmen killed a policeman in Mosul. Two civilians died in separate incidents in the northern city of Kirkuk.

Meanwhile, demonstrations were held in several Iraqi cities by Sunni Arabs, who have complained of fraud in the recent parliamentary vote. Shi'ite Arabs in Baghdad also marched Sunday to show support for Shi'ite candidates.

Initial results showed a key Shi'ite coalition was leading the vote.

In northern Iraq, Iraq's President Jalal Talabani said Iraq's new government should include all of Iraq's religious and ethnic groups.
