DAMASCUS, August 16. /TASS/. Chemical agents found at arms depots abandoned by militants suggest they were delivered to terrorists in Syria from the United States and the United Kingdom, Syrian Deputy Foreign Minister Faisal Mekdad said at a press conference in Damascus on Wednesday.

"All the special means that have been found include hand grenades and rocket projectiles for grenade launchers, which are supplied with CS and CN irritant agents [they are shown in transparencies]. The discovered chemical munitions shown in the transparency were produced by Federal Laboratories on the US territory. And the chemical agents were produced by Cherming Defence UK and NonLethal Technologies (the USA)," Mekdad said.

According to the Syrian deputy foreign minister, the chemical agents were found at terrorists’ depots both in Aleppo and in liberated districts in the eastern suburb of Damascus.

As Mekdad said, in compliance with article 5 of the convention on the prohibition of chemical weapons, the use of irritant agents is allowed only for fighting riots. They are prohibited for use as warfare means.

"Therefore, it can be said with confidence that the United States and the United Kingdom, and also their allies in the region, are rendering all possible support to terrorist organizations active in Syria, thus violating the convention on the prohibition of chemical weapons. They are supplying terrorists not only with conventional arms but also with banned chemical agents," Mekdad said.
