About 600 people from Jolani's special forces will enter Saudi Arabia next week.
The Associated Press news agency, citing a Syrian official, announced the agreement between Damascus and Riyadh to deploy hundreds of Syrian commandos in Saudi Arabia.
The Saudi government announced as a clear precondition that all members of the delegation must be originally Syrian citizens and that no foreign fighters be found among them.
36 senior military officials of the Julani government visited the operational areas and the war fronts during a visit to the city of Jeddah.
