NEAR NAJAF, Iraq (Reuters) - U.S. forces poised outside Najaf say they will allow time for talks before any attempt to enter the holy Iraqi city to seize a rebel cleric -- a move that could spark new unrest. [...]
[Col. Dana] Pittard [, commander of the 3rd Brigade Task Force,] said his 2,500-strong force would be replaced by around 2,000 1st Armoured Division soldiers in coming days.
The U.S. military, fighting Sunni guerrillas in western Iraq and Sadr's militiamen in Shi'ite areas of the country, has lost more troops in combat in the last three weeks than in the three-week war that toppled Saddam Hussein.
Since March 31, 104 U.S. troops have been killed in action.
Fighting on Saturday killed 10 American soldiers, including five Marines who died in clashes near the Syrian border.

"However, one day does not a trend make," he said.
