The Global Security website, which collects published intelligence reports and other data, says there are four suspected chemical weapons sites in Syria: north of Damascus, near Homs, in Hama and near the Mediterranean port of Latakia. Weapons it produces include the nerve agents VX, sarin and tabun, it said, without citing its sources.
Abdelbasset Seida, head of the Syrian National Council opposition group, said, "A regime that massacres children and rapes women could use these types of weapons.
"The technical infrastructure may not be suitable, but as I said, such a step could be expected from this murderous regime. The international community must prevent this," he told reporters after meeting Turkey's foreign minister in Ankara.
Arab League ministers meeting in Doha urged the opposition and the rebel Free Syrian Army to form a transitional government, Qatari Prime Minister Sheikh Hamad bin Jassim al-Thani told a news conference.
