A senior Iranian lawmaker has dismissed allegations of a decline in the number of Iranian military advisors in Syria, saying the claims are aimed at undermining the anti-Daesh campaign in Syria, Press TV reported Friday.

Alaeddin Boroujerdi, who chairs the Foreign Policy and National Security Committee of Iran's parliament (Majlis), said on Thursday that a "psychological war" was initiated as soon as Iran, Russia, Syria and Iraq joined hands to fight terrorism.

He said that this psychological war stems from the failure of the US and its allies in their so-called fight on terrorism while the "four-nation alliance [of Iran, Russia, Syria and Iraq] has managed to achieve massive and effective victories in a short period of time."

Iran has sent military advisors to Syria to provide assistance to in the fight against militant groups operating there.

Russia has also been conducting airstrikes against these groups positions in Syria since September 30, upon a request from Damascus.

Also on Thursday, Iran's Deputy Foreign Minister for Arab and African affairs Hossein Amir-Abdollahian reiterated the country's support for the Syrian government in its fight against "terrorists whose hands are stained with the blood of oppressed Syrian people."
