Deputy Foreign Minister for Arab and African Affairs Hossein Amir Abdollahian and Deputy Swiss Foreign Minister Yves Rossier expressed concern over the expansion of extremism in Syria, and emphasized the need for cooperation and continued exchange of ideas between the two countries to help Syria find its way out of the prolonged crisis. Referring to the August chemical weapons attacks in a suburb of Syrian capital Damascus, Amir Abdollahian said Iran as a major victim of such weapons condemns the use of such weapons anywhere and by anyone, adding, “We had several times warned that the terrorists fighting in Syria had been armed with chemical weapons by some foreign players.”

In a suspected chemical attack on several towns of the Ghouta agricultural belt to the west and east of Damascus on August 21, hundreds of people were killed, something that took the US to the brink of attacking Syria, before it agreed with a Russian proposal that entailed destruction of Syria's chemical weapons arsenal. The two countries’ deputy foreign ministers also exchanged ideas on Iran-Switzerland relations and the need for expansion of bilateral ties during the meeting.
