Adm. Michael Mullen, chairman of the Joint Chiefs of Staff, told reporters the deployment should not be viewed as threatening or in response to events in any single country in that volatile region.

"This is an area that is important to us, the eastern Med," he said when asked about news reports of the ship movements. "It's a group of ships that will operate in the vicinity there for a while," adding that "it isn't meant to send any stronger signals than that. But it does signal that we're engaged, we're going to be in the vicinity and that's a very, very important part of the world."

Another military officer, speaking on condition of anonymity because full details about the ship movements are not yet public, said a Navy guided missile destroyer, the USS Cole, was headed for patrol in the eastern Mediterranean and that the USS Nassau, an amphibious warship, would be joining it shortly. The officer said a third ship would go later, but he did not identify it by type or name.

The U.S. Sixth Fleet, whose area of operations includes the entire Mediterranean, is based at Naples, Italy.

The decision to send the ships appeared to be a not-too-subtle show of U.S. force in the region as international frustration mounts over a long political deadlock in tiny, weak Lebanon. The U.S. blames Syria for the impasse, saying Syria has never given up its ambitions to control its smaller neighbor.

The presidential election in Lebanon has been delayed 15 times. Just this week the date was pushed back to March 11.

Secretary of State Condoleezza Rice is due to visit the Middle East next week.

Mustafa Alloush, a member of the Lebanese Parliament from the U.S.-backed majority, told the majority's Future television that neither the government nor the anti-Syrian majority had any links to the dispatching of the Cole.

"But we remind what caused the situation to bring the American equation into the arena," he said, blaming Syria indirectly for inviting such American intervention. "It (the deployment) could be aimed directly at Syria or a declaration by the United States of America that it could be part of this equation that could develop if conditions remain the way they are," Alloush said.

Mullen was asked whether the deployment of the ships was linked to the timing of the Lebanese election.

"To say it's absolutely directly tied would be incorrect, but we are certainly aware that elections out there are both important and they are due at some point in time," he replied.

And when asked whether Syria is the reason for the deployment, he said, "It's not specifically sent to any one country, as much as it is to the region itself."

The Cole was rebuilt after nearly being sunk in a terrorist attack in Aden, Yemen, in October 2000. It was recommissioned in April 2002 and went on its first post-attack deployment in November 2003.

National Security Council spokesman Gordon Johndroe said the deployment of the Cole is meant as "a show of support for regional stability." He added that President Bush is concerned about the situation in Lebanon.

The Cole, whose homeport is Norfolk, Va., is sailing to the region from Malta.
