Iraqi Kurdish negotiators say they will resume talks Monday with the country's dominant Shi'ite alliance to hammer out details of a coalition government.
One of the negotiators, Fuad Masoum, says there are further, important issues that need to be resolved before a government is formed.
Negotiators have been hoping to agree on a government before Iraq's National Assembly convenes for the first time on Wednesday.
Meanwhile, a roadside bomb south of Baghdad killed two American security contractors Sunday. To the north, in Mosul, witnesses say three Iraqi civilians were killed when a U.S. helicopter fired on insurgents.
Also Sunday, a previously-unknown group claimed responsibility for last week's bomb attack on a Shi'ite funeral that killed 50 people. It says the attack was to demonstrate opposition to Shi'ites who are set to take control of Iraq's new government.
