Where are ISIL terrorists chemical weapons made in?

An analyst says the Takfiri ISIL terrorist group has used US-made chemical weapons in a series of chemical attacks across Syria.
Gordon Duff, a senior editor at Veterans Today, said in an interview with Press TV that the chemical weapons being used by the ISIL “are made in the US-owned labs outside Tbilisi, Georgia.”
These chemical and biological weapons are then shipped and moved by the CIA-run networks through their regional allied countries into Syria, Duff said.
He strongly criticized the Western government for their “desperate silence” over the issue, saying they have “done nothing” to stop these shipments.
The remarks come as pictures of Kurdish fighters killed in battles with the ISIL militants suggest that the terrorists used chemical weapons against Kurds in the Syrian border town of Kobani.
