On Wednesday, the Syrian Foreign Ministry has accused the US and the UK of supplying CS, CN toxic agents to terrorists.

According to Syria's Ministry of Foreign Affairs, the toxic agents found in Aleppo and Damascus suburb were produced by one British company and two American companies.

"The special equipment found consisted of hand grenades and rounds for grenade launchers equipped with CS and CN toxic agents […] The chemical munitions were produced by the Federal Laboratories company in the US. The toxic agents were produced by Cherming Defence UK and NonLethal Technologies (US)," Syrian Deputy Foreign Minsiter Faisal Mekdad said.

According to the deputy foreign minister, the poisonous substances were found in the storehouses of the militants in Aleppo and in the eastern suburbs of Damascus.

Mekdad noted that in accordance with Article 5 of the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons, the use of toxic agents is permitted only to combat riots. It is prohibited to use them in warfare.

"So, we can say for sure that the US and UK as well as its allies in the region violate the Chemical Weapons Convention. They support terrorist organizations operating in Syria. They deliver to the militants not only armaments but also prohibited toxic agents," the deputy foreign minister added.
