DAMASCUS, Syria (AP) -- U.N. experts investigating purported poison gas attacks have left their Damascus hotel, but anti-regime activists say the team's destination was not immediately known.
The inspectors spent two days this week taking biological samples and interviewing survivors in the suburbs of Damascus where Syrian activists say hundreds were killed in the Aug. 21 attacks.
Associated Press photographers say the team left the hotel Thursday morning in six cars with U.N. markings. The team's two-week mandate ends this weekend.
U.S. President Barack Obama said Wednesday he has concluded the Syrian regime is behind the attack. It's not clear if the Western powers will wait for the U.N. experts' findings before launching a possible punitive military strike.
The U.S. has signaled it would act even without backing from its allies or the U.N.
