Over the last 72 hours inside the Rif Dimashq Governorate's western countryside, the so-called "Islamic State of Iraq and Al-Sham" (ISIS) and their former allies from the Syrian Al-Qaeda group "Jabhat Al-Nusra" have been reportedly involved in a serious confrontation near the Jaroud Jarajeer and Jaroud Qarah border-crossings into Lebanon.
On Friday, the two terrorist groups intensified their attacks against one another at Jaroud Jarajeer, resulting in a substantial number of dead on both sides.
The clashes began when the Jabhat Al-Nusra terrorists launched an attack to regain control over the sites that were captured by ISIS during Thursday's confrontation between the two sides.
However, Jabhat Al-Nusra was unable to recapture any territory they lost to the ISIS terrorists; instead, they found themselves retreating once again, when ISIS forestalled their advance near the Lebanese border.
It is worth noting that the two terrorist groups are still occupying a narrow area in the Qalamoun barrens after Hezbollah and the Syrian Army seized most of it during their large-scale campaign in the summer of 2015.
Firefights are still ongoing between the two terrorist groups, despite the fact that they are being bombarded by the Syrian and Lebanese armies across both borders of the Qalamoun Mountains.
