It was unclear where the team, which left in a three-car convoy, was headed.
The experts arrived in Syria yesterday on their second mission to the country, where they will examine some 14 alleged incidents involving the use of chemical weapons.
On their earlier mission, the team investigated an August 21 attack in the outskirts of Damascus that reportedly killed hundreds of people.
Its report, submitted to the United Nations, confirmed that sarin was used, but did not apportion blame for the attack.
