Iraq insists on U.S. withdrawal timetable

BAGHDAD (Reuters) - Iraq will not accept any security agreement with the United States unless it includes dates for the withdrawal of foreign forces, the government's national security adviser said on Tuesday.

But the government's spokesman said any timetable would depend on security conditions on the ground.

Their differences underscore the debate in Baghdad over a deal with Washington that will provide a legal basis for U.S. troops to remain when a U.N. mandate expires at the end of the year.

But Washington played down calls from Baghdad for a firm withdrawal deadline, saying both sought greater Iraqi security.

U.S. Defense Secretary Robert Gates said on Tuesday he expected to pull more U.S. troops from Iraq and stressed any decision to withdraw would be based on the ability of Iraqi troops to take responsibility for security and combat.

On Monday, Prime Minister Nuri al-Maliki suggested for the first time that a timetable be set for the departure of U.S. forces under the deal being negotiated, which he called a memorandum of understanding.

National Security Adviser Mowaffaq al-Rubaie appeared to go further on Tuesday.

"We can't have a memorandum of understanding with foreign forces unless it has dates and clear horizons determining the departure of foreign forces. We're unambiguously talking about their departure," he told reporters in Najaf after meeting Iraq's top Shi'ite cleric, Grand Ayatollah Ali al-Sistani.
