ISIS used banned mustard gas in Syria
Fears have been confirmed with the release of an official report regarding ISIS’s use of mustard gas in Syria earlier this year. The Organisation for the Prohibition of Chemical Weapons (OPCW) announced that "at least two people were exposed to sulphur mustard" in the town of Marea, north of Aleppo, last August. This is the second time that ISIS has been found to have used banned chemical weapons in Syria. Recently, two Turkish MP's claimed that Turkey had supplied ISIS with the chemicals.

Veteran’s Today (VT) Senior Editor and security consultant Gordon Duff told Sputnik on Friday that Turkish agents have not only distributed chemical weapons to the ISIL, but have helped the militants manufacture them.

Lethal chemical substances were initially being produced within Turkey itself, Duff said, before they moved operations across the border into Raqqah, Syria, where the ISIL is reportedly headquartered.

"Mustard gas and chlorine come from Raqqah… at a Turkish-run facility," Duff explained, citing a Syrian army general who informed VT’s Bureau Chief in Damascus Nayed al Hussaini.

In March, Duff added, Syrians captured a Turkish chemical weapons officer at another facility in the region.

Geopolitical analyst and editor Eric Draitser told Sputnik that it was entirely possible Turkish intelligence agents to have supplied chemical weapons to terrorist groups like the al-Nusra Front and the ISIL, either directly or through foreign agents operating on the Syrian-Turkish border.

"Either way, the hands of the Turkish government are not clean," Draitser claimed. "President [Recep Tayyip] Erdogan in Turkey has a lot to answer for."

On Thursday, the Russian Foreign Ministry said it had evidence that the ISIL acquired documentation related to manufacturing chemical weapons.

The ISIL reportedly used chemicals during an attack on the northeastern Syrian town of Marea on Tuesday.

In August, US officials confirmed that mustard gas had been used to attack Kurdish forces fighting the ISIL in northern Iraq.

The Assad government decided to destroy the country’s chemical weapons stockpile after a sarin gas attack near Damascus killed hundreds of people in 2013. The Syrian government and anti-government rebels, which include numerous Islamic extremists, have traded blame for the sarin attack.

At the end of October 2014, international monitors reported that nearly 98 percent of chemical weapons removed from Syria had been destroyed.
