KUALA LUMPUR - The Pentagon is prepared to carry out military options on Syria should President Barack Obama order them, US Defence Secretary Chuck Hagel said on Sunday.
Hagel echoed White House statements cautioning that America was still gathering the facts about the Syrian government's alleged use of poison gas against civilians.
But he noted that the US military, which is repositioning its naval forces in the Mediterranean to give Obama the option for an armed strike, was ready to act if asked.
"President Obama has asked the Defence Department to prepare options for all contingencies. We have done that and we are prepared to exercise whatever option - if he decides to employ one of those options," Hagel told reporters at a news conference in Kuala Lumpur.
American and European security sources have said US and allied intelligence agencies made a preliminary assessment that chemical weapons were used by Syrian forces in the attack. The United Nations has requested access to the site.
Hagel, whose week-long trip to Asia is being overshadowed by Syria tensions, participated remotely in a meeting on Saturday that Obama held with his top military and national security advisers to hash out options on Syria.
Asked whether, after that meeting, he was personally convinced chemical weapons had been used in Syria, Hagel said: "We, along with our allies, are continuing to assess the intelligence, and the specifics of that intelligence, on the use chemical weapons."
"I wouldn't go any further than that until we have more intelligence, based on facts," he said.
Obama has been reluctant to intervene in Syria's civil war, but reports of the killings near Damascus have put pressure on the White House to make good on the president's comment a year ago that chemical weapons would be a "red line" for the United States.
Hagel did not enter into detail about what options the United States was weighing, but noted that any scenario carried risks. He noted on his flight to Malaysia that if Syrian President Bashar al-Assad's forces intentionally used chemical weapons, "there may be another attack coming".
"There are risks and consequences for any option that would be used -- or not used. For action or inaction," Hagel said on Sunday.
"All of those assessments are being made. They will be driven by … the facts, what our intelligence assessment produces, law, legal issues, international support."
