(MNA) -- Secretary of Iran’s Supreme National Security Council (SNSC) Ali Shamkhani made the remarks on Wednesday in reaction to the recent threats made by US against the Syrian government, accusing it of making “preparations for another chemical weapons attack” and noting that Syria would “pay a heavy price” if such an assault took place.

Shamkhani stressed the need for OPCW (Organisation for the Prohibition of Chemical Weapons) investigation into the US claims, adding “if the US is truly sincere in the claims it makes, it must provide OPCW inspectors with all related information so that the claims can be verified with cooperation from the Syrian government.”

He reminded the US illegal invasion of Syrian territory by carrying out cruise missile strikes against Shayrat airfield on April 7 under the pretext of alleging Syrian government of conducting a gas attack on the town of Khan Shaykhun in Idlib Province on April 4, adding “following the incident, Iran and Russia made official requests for dispatch of an international fact-fining mission to Syria to investigate the US claims, but Washington blocked the measure to cover up the falsehood of those claims.”

Shamkhani further stressed that the military scene in Syria would soon make a change in the continuation of US one-sided aggression in the warn-torn country and its escape from consequences of its measures.
