Ibrahim al-Adavi nom de guerre Abu Musa was gunned down by unknown raiders near the village of Safouhan in Jabal al-Zawiyah on Tuesday, the sources said.
They added that, meantime, Tahrir al-Sham Hay'at (the Levant Liberation Board or the Al-Nusra Front) has started storming the positions of rival terrorists from the ISIL in Southern Idlib, arresting a number of them.
The sources said that fresh wave of tension has covered the town of Fua'a North of Idlib city after Tahrir al-Sham expelled the families of tens of terrorists from the town.
Last week, Al-Watan online quoted sources, affiliated to Ahrar al-Sham terrorist group which is supported by the Turkey-backed National Liberation Front, as disclosing that Tahrir al-Sham has rolled down the flag of the Turkey-backed militants from its bases and used a new black flag after a meeting in Bab al-Hawa near the border with Turkey over reforming its command structure known as the Liberation Front.
It went on to say that Tahrir al-Sham's move in defiance of the Turkish Army was considered as declaring war against the Ankara-backed militants in Northern Syria that can trigger tough battle between Tahrir al-Sham and Ankara forces in the region.
Al-Watan said that Tahrir al-Sham's move has enraged the commanders of the Ankara-backed militants, specially commanders of the National Liberation Front, who blame Tahrir al-Sham for thwarting Ankara's attempts to unite all terrorist groups under a flag in occupied regions in Northern Syria.
Al-Watan said that Tahrir al-Sham's control over two-thirds of Idlib's territory along with other regions in Hama, Lattakia and Aleppo provinces has pushed other terrorist groups into panic in Northern and Northwestern Syria.
