The Syrian Army and the National Defense Forces (NDF), backed by Russian warplanes, seized high points at the Hayyal Mountain near the ISIS-held ancient city of Palmyra on Sunday.
Controlling this strategic mountain, the army and the NDF were able to set a fire control over the Palmyra Triangle, an important site at the western gates of Palmyra.
Government troops also liberated the Quarries area northwest of Palmyra. These advances clearly show that government forces are set to kick off the operation to retake the ancient city from ISIS terrorists.
