The Lebanese Army troops deployed at mountainous regions at border with Syria to kick off a large-scale operation against ISIL-held territories in Arsal Barrens after Al-Nusra Front (Tahrir al-Sham Hay'at or the Levant Liberation Board) was forced to leave the region for Syria's Idlib under the heavy attacks of Hezbollah fighters, field sources said Friday. The sources reported that the Lebanese Army is now set to launch a new offensive in Eastern Lebanon that will target ISIL's last positions in the Ra'as Ba’albak area of the province. Meantime, well-informed sources said that Hezbollah has moved many of its troops from the region in order to allow the Lebanese Army to establish control over the border. Relevant reports said on Thursday that the al-Nusra Front terrorist group ended its presence at the bordering heights between Lebanon and Syria and evacuated the region. Based on an agreement made between the resistance forces in Lebanon and the Al-Nusra commanders in Arsal heights at the borders between Lebanon and Syria, more than 7,800 militants and their family members, including Al-Nusra Emir Abu Malik al-Tali, left the region towards the Syrian territories on 116 buses on Wednesday. Meantime, the resistance forces regained control of several points and positions, including Hasan al-Kharbah, Moshref, Aqabah Nouh Asnayn, Zahr Wadi overlooking Wadi al-Hamid and Wadi al-Marah districts after the first group of militants left the region. They also started cleansing operations in the area.
