Obama met with top advisers including Vice President Joe Biden, national security adviser Susan Rice, and CIA Director John Brennan to hash out responses.
Obama has been reluctant to intervene in Syria’s civil war, which he has described as a “sectarian complex problem.” But he said a year ago that chemical weapons would be a “red line” for the United States.
Syrian opposition accounts that between 500 and well over 1,000 civilians were killed this week by gas in munitions fired by pro-government forces, and video footage of victims’ bodies, have stoked demands abroad for a robust, US-led response after 2-1/2 years of international inaction on Syria’s conflict.
The White House said Obama spoke with British Prime Minister David Cameron about Syria yesterday and both men expressed “grave concern” about the reports of chemical weapons use.
“In coordination with international partners and mindful of the dozens of contemporaneous witness accounts and record of the symptoms of those killed, the US intelligence community continues to gather facts to ascertain what occurred,” the White House said in a statement.
“The president also received a detailed review of a range of potential options he had requested be prepared for the United States and the international community to respond to the use of chemical weapons.”
After completing a bus tour through New York state and Pennsylvania on Friday, the president returned to a White House that was concentrating on its latest foreign policy crisis.
Vehicles pulled up in front of the West Wing yesterday morning, bringing officials to the meeting. Secretary of State John Kerry, who is on vacation in Massachusetts, and Secretary of Defense Chuck Hagel, who is travelling in Asia, both participated remotely.
The White House declined to say when the meeting ended, although it appeared to have lasted about three hours. Director of National Intelligence James Clapper was seen exiting the building around 12.45 pm.
Other participants included Samantha Power, the US representative to the United Nations; Chairman of the Joint Chiefs of Staff Martin Dempsey; and Deputy Attorney General James Cole.
Administration officials were cautious in describing the content of the discussions.
“We have a range of options available, and we are going to act very deliberately so that we’re making decisions consistent with our national interest as well as our assessment of what can advance our objectives in Syria,” a White House official said before the meeting yesterday.
Obama said in a CNN interview broadcast on Friday that the United States was still gathering information about the apparent chemical weapons attack that killed as many as 1,000 civilians in a Damascus suburb.
He noted, however, that chemicals weapon use on a large scale would start “getting to some core national interests that the United States has, both in terms of us making sure that weapons of mass destruction are not proliferating, as well as needing to protect our allies, our bases in the region.”
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.
