The Qastal Ma'af road and Lattakia-Kassab highway, which were not operational for at least two years, have now been reopened.
"The recapture of Turkmen mountain (Jabal al-Turkmen) by the Syrian forces played a significant role in reopening the [Lattakia-Kassab] highway," the media outlet quoted the source as saying.
Militants are reported to have fled to the town of Rabia following the government offensive. Damascus-led forces are planning to focus their efforts on liberating the town.
The Syrian Arab Army also pushed terrorists out of Height 713 and al-Koz mountain after Russian warplanes launched airstrikes against militant targets in the area.
