BEIRUT (AP) -- U.N. experts investigating an alleged chemical weapons attack have left Syria after four days of visits to the sites.
The team is headed for the Netherlands where blood and urine samples from victims and soil samples from the sites will undergo lab analysis. The U.N. has said it will try to expedite its final report.
The U.S. has accused the Syrian government of carrying out the attack and President Barack Obama says he is weighing "limited and narrow" action against President Bashar Assad's regime. U.S. warships carrying cruise missiles are in place in the Mediterranean Sea.
France is, so far, Obama's only major public ally. U.N. chemical experts left Syria today after several days of gathering evidence for further analysis.
