Iran stated on Saturday that there is "proof" that Syrian militants used chemical weapons in their war against the Syrian government, reassuring that “we are very concerned about information regarding the use of chemical weapons in Syria, and we strongly condemn the use of such weapons.”

Iranian Foreign Ministry Spokesman, Abbas Araqchi, was quoted by ISNA news agency as saying that there is proof terrorist groups carried out this action,’ Araqchi said in reference to Wednesday's allegedly deadly attacks in the Damascus area.

Iran also warned against any Western military intervention in the Syrian conflict, after the United States suggested it was weighing up such a possibility.

"There is no international authorization for a military intervention in Syria. We warn against any actions or statements that could create more tension in the region. I hope that White House officials show enough wisdom not to enter into such dangerous tumult," Araqchi added.

He further considered that "the provocative words of American officials or sending warships do not help to solve the problem in any way, but make the situation in the region more dangerous.”

“Iran has declared on several occasions that the crisis in Syria did not have a military solution," Araqchi was quoted as saying.
