Iran has been involved in the Syria civil war since it started. Its militias have backed and propped up Syrian dictator Bashar al Assad to no end and at the minute their combined forces are subduing towns and cities from Eastern Aleppo to southern ar-Raqqah. Russian battleships in the Mediterranean, as well as jets, are working to subjugate them with shells.
The brave Syrian opposition is battling away through tough circumstances even after it was assailed by Iran and its foreign militias. The opposition has been unable to receive much needed aid and supplies because the Jordanian and Turkish passages have remained closed.
