BAGHDAD - Iraq's prime minister said Monday his country wants some type of timetable for a withdrawal of American troops included in the deal the two countries are negotiating.

It was the first time that Prime Minister Nouri al-Maliki has explicitly and publicly called for a withdrawal timetable -- an idea opposed by President Bush.

He offered no details. But his national security adviser, Mouwaffak al-Rubaie, told The Associated Press that the government is proposing a timetable conditioned on the ability of Iraqi forces to provide security.

The U.S. State Department declined to comment on the negotiations.

Al-Maliki said in a meeting with Arab diplomats in Abu Dhabi that his country has also proposed a short-term interim memorandum of agreement rather than the more formal status of forces agreement the two sides have been negotiating.

The memorandum "now on the table" includes a formula for the withdrawal of U.S. troops, he said. "The goal is to end the presence" of foreign troops, al-Maliki said.

Some type of agreement is needed to keep U.S. troops in Iraq after a U.N. mandate expires at year's end. But many Iraqi lawmakers have criticized the government's attempt to negotiate a formal status of forces agreement, worried that U.S. demands would threaten the country's sovereignty.

Adm. Michael Mullen, chairman of the Joint Chiefs of Staff, did not comment directly on the agreement's specifics when asked about them on a trip to Baghdad.

"We'd all like to see U.S. troops get out of here at some point in time," Mullen said. "However, from a military perspective, I need the laws and the regulations and the agreements from the government of Iraq in order to continue operations beyond the 31st of December of this year."
