The chemical weapon experts visited a storage containing chemical substances in Syria, pro- government Sham FM radio said Tuesday.

The radio cited a video footage that went viral on the web, in which experts wearing anti-gas masks seemed examining some barrels with special devices.

The radio report didn't specify what kinds of substances the experts were examining, but it said they may contain chemical materials or substances that could be used in manufacturing chemical weapons.

The video footage didn't disclose information about the location of the storage or the exact date of the experts' visit to that place.

Earlier in the day, the Organization for Prohibition of Chemical Weapons (OPCW) said in a statement that it will deploy a second team of inspectors in Syria.

"OPCW deploys a second team of inspectors to expand verification and destruction activities in Syria," the statement said.

It will bolster the OPCW experts who have been in Syria since Oct. 1 to conduct verification and destruction activities, according to the statement

The first group of chemical experts arrived in Syria last Tuesday and met with Syrian foreign ministry officials before they started their ground work on Oct. 6 to find and dismantle an estimated 1,000-ton chemical arsenal in the country.

The United Nations Security Council said the OPCW will help Syria destroy its chemical weapons by mid-2014. The mission will be expanded as more investigators will arrive in Damascus next week.
