The UN experts investigating last week's alleged chemical weapons strike outside Damascus left Syria early Saturday and crossed into neighboring Lebanon, departing hours after President Barack Obama said he is weighing "limited and narrow" action against a Syrian regime that the administration has bluntly accused of launching the deadly attack.
An Associated Press crew saw the UN personnel enter Lebanon from Syria through the Masnaa border crossing and then drive in a 13-car convoy to the Beirut airport. After four days of on-site inspections, the team wrapped up its investigation Friday into the suspected chemical weapons attack on rebel-held suburbs of Damascus on Aug. 21. The experts take with them blood and urine samples from victims as well as soil samples from the affected areas for examination in laboratories in Europe.
The inspectors' departure brings the looming confrontation between the U.S. and President Bashar Assad's regime one step closer to coming to a head.
Obama has said that if he opts for a military strike, any operation would be limited in scope and only aimed at punishing Assad for his alleged use of chemical weapons.
But any U.S. action carries the potential to trigger retaliation by the Syrian regime or its proxies against U.S. allies in the region, such as Jordan, Turkey and Israel. That would inject a dangerous new dynamic into a Syrian civil war that has already killed more than 100,000 people, forced nearly 2 million to flee the country and inflamed sectarian tensions across the Middle East.
While Obama has long been wary of U.S. military involvement in the conflict, the administration on Friday forcefully made its case for action against Syria in the wake of last week's events outside Damascus. It accused the Assad regime of carrying out what it says was a chemical attack on Aug. 21 that killed at least 1,429 people — far more than previous estimates — including more than 400 children.
With France as his only major public ally, Obama told reporters he has a strong preference for multilateral action.
"Frankly, part of the challenge we end up with here is a lot of people think something should be done but nobody wants to do it," he said.
The U.S. already has warships in place in the eastern Mediterranean Sea near Syria's coastal waters. The vessels are armed with cruise missiles, long a first-line weapon of choice for presidents because they can find a target hundreds of miles distant without need of air cover or troops on the ground.
The Syrian government said administration claims were "flagrant lies" akin to faulty Bush administration assertions before the Iraq invasion that Saddam Hussein had weapons of mass destruction. A Foreign Ministry statement read on state TV late Friday said that "under the pretext of protecting the Syrian people, they are making a case for an aggression that will kill hundreds of innocent Syrian civilians."
In Damascus, residents stocked up on food and other necessities in anticipation of strikes, with no evident sign of panic.
One man, 42-year-old Talal Dowayih, said: "I am not afraid from the Western threats to Syria; they created the chemical issue as a pretext for intervention, and they are trying to hit Syria for the sake of Israel."
Obama met with his national security aides at the White House and then with diplomats from Baltic countries, saying he has not yet made a final decision on punitive strikes.
But the administration did nothing to discourage the predictions that action was imminent.
That impression was heightened both by sharply worded remarks from Secretary of State John Kerry and the release of an unclassified intelligence assessment that cited "high confidence" that the Syrian government carried out the attack.
In addition to the dead, the assessment reported that about 3,600 patients "displaying symptoms consistent with nerve agent exposure" were seen at Damascus-area hospitals after the attack.
In his remarks, Kerry added that "a senior regime official who knew about the attack confirmed that chemical weapons were used by the regime, reviewed the impact and actually was afraid they would be discovered."
The assessment did not explain its unexpectedly large count of 1,429 deaths, far in excess of an estimate from Doctors Without Borders. Not surprisingly — given the nature of the disclosure — it also did not say expressly how the United States knew what one Syrian official had allegedly said to another.
Mindful of public opinion, Kerry urged Americans to read the four-page assessment for themselves. He referred to Iraq — when Bush administration assurances that weapons of mass destruction were present proved false, and a U.S. invasion led to a long, deadly war. Kerry said this time it will be different, and that "we will not repeat that moment."
Citing an imperative to act, the nation's top diplomat said "it is directly related to our credibility and whether countries still believe the United States when it says something. They are watching to see if Syria can get away with it because then maybe they, too, can put the world at greater risk."
While Obama was having trouble enlisting foreign support, French President Francois Hollande was an exception. The two men spoke by phone, then Hollande issued a statement saying they had "agreed that the international community cannot tolerate the use of chemical weapons, that it must hold the Syrian regime responsible and send a strong message to denounce the use of (such) arms."
Friday's events produced sharply differing responses from members of Congress, even within the same party.
Sens. John McCain of Arizona and Lindsey Graham of South Carolina, both Republicans, said Obama needed to go further than he seems planning, saying the goal should be "to shift the balance of power on the battlefield against Assad and his forces."
But a spokesman for Republican House Speaker John Boehner, Brendan Buck, said if the president believes in a military response to Syria, "it is his responsibility to explain to Congress and the American people the objectives, strategy, and legal basis for any potential action."
Obama has long been wary of U.S. military involvement in Syria's civil war, as he has been with tumultuous events elsewhere during the so-called Arab Spring. In the case of Syria, his reluctance stems in part from recognition that while Assad has ties to Iran and the Lebanese militant group Hezbollah, the rebels seeking to topple him have connections with al-Qaida-linked groups.
Still, Obama declared more than a year ago that the use of chemical weapons would amount to a "red line" that Assad should not cross. And Obama approved the shipment of small weapons and ammunition to the Syrian rebels after an earlier reported chemical weapons attack, although there is no sign the equipment has arrived.
