The ancient Assyrian city of Quraytayn was captured by the Islamic State of Iraq and Al-Sham (ISIS) in early August of 2015; and since its capture by the aforementioned terrorist group, the Syrian Armed Forces have struggled to retake this vast desert area that stretches as far south as the Homs Governorate's border with the Iraqi province of Al-'Anbar.
However, the Syrian Armed Forces' woes changed after the second capture of Maheen last month; this victory by the government forces exposed ISIS' inability to hold ground for a long period time due to manpower shortages and a scarcity in military resources.
Last week, the Syrian Arab Army's 120th Brigade of the 2nd Armored Division - in close coordination with the National Defense Forces (NDF) of Sadad and the Syrian Social Nationalist Party (SSNP) - imposed full control over the Maheen-Quraytayn Checkpoint that ultimately leads to the ancient Assyrian city and its surrounding mountains.
Earlier this morning, the Syrian Arab Army's 120th Brigade and their allies continued their assault on ISIS' last line of defense at Jabal Quraytayn, striking the terrorist group near this mountain's southeastern perimeter.
As a result of their military operations in the Homs Governorate's southeastern countryside, the Syrian Armed Forces have almost completely enveloped Quraytayn, leaving ISIS with only one route to retreat.
This is not uncommon for the Syrian Armed Forces to leave one road open at a site they're attacking; this military tactic is supposed to encourage the enemy forces to retreat and several times during this war, it has worked for them.
