The Supreme National Security Council (SNSC) of Iran announced that is has appointed its secretary Ali Shamkhani as the senior coordinator for political, military and security affairs with Syria and Russia.
A statement by SNSC said that this is the first time the position has existed.
The announcement came after Shamkhani met Russian Defence Minister Sergey Shoygu and his Syrian counterpart Fahd Jassem al-Freij in Tehran to discuss the "war on terror", as well as other developments in Syria.
Commenting on the new appointment, Al-Jazeera's Tehran Bureau Chief Abdul Qader Fayez explained that creating the position means that politics may influence the course of events in Syria.
"The Iranian Revolutionary Guard has so far been the main controller of events in Syria, but after this post, politics may have more influence," he explained.
The defence ministers of Russia, Syria and Iran held a meeting in Tehran on Thursday to discuss the fight against terrorism in the Middle East, during which Tehran and Moscow renewed their support for the Syrian regime.
