It was not stated when the military exercise will begin or for how long it will take place, but Saudi Arabia also announced that it will intensify efforts in Syria as part of its ongoing operations against the Islamic State Group.
Twenty countries will be taking take part, SPA said.
The shift would be from air to ground operations implying the deployment of Saudi troops inside Syria.
Under this evolving scenario, there is also the possibility of Turkey and Saudi Arabia forces acting on behalf of US-NATO could be involved in military confrontations with both Russian Federation and Iran, a door towards military escalation. “Saudi Arabia and Gulf countries will continue to support the Syrian revolution even without the USA green light and will not allow Syria to be eaten by Iran and ISIL”.
Saudi Arabia has also expressed willingness to work with Turkey in that regard.
