The top U.S. administrator in Iraq says former Iraqi President Saddam Hussein is likely still alive and hiding out in Iraq.

But administrator Paul Bremer says there is no public support in Iraq for Saddam, and vows that the ousted leader is not coming back.

Speaking Sunday, Mr. Bremer told NBC's Meet the Press that Americans should prepare for a long presence in post-war Iraq. He said he did not know how many years the U.S.-led mission will take.

Earlier today, two U.S. soldiers were killed in northern Iraq when their convoy came under attack.

Several hours later, near the town of Hilla, south of Baghdad, United Nations officials say a U.N. aid worker was wounded when a two car convoy was attacked. The Iraqi driver of one of the vehicles was killed.

Meanwhile, in the southern Iraqi city of Najaf, more than 10,000 demonstrators gathered today in support of an influential cleric who has strongly criticized the U.S. occupation of the country.

The protesters marched on the local offices of the American-led administration, where they were kept back by U.S. troops.

The protesters accuse American soldiers of surrounding the house of cleric Moqtada al-Sadr on Saturday, following a fiery speech he delivered on Friday criticizing the U.S.-led coalition in Iraq.
