>> On board these buses, Syrian militants and refugees crossing the border from Lebanon into Syria. They're headed for Idlib in the northwest, a rebel held area. Seeing them off, Hezbollah fighters and personnel. Shiite Hezbollah routed the Sunni Islamist Nusra Front in the mountains around Arsal last week. This area their last foothold on the frontier.
Some 7,000 Syrians, a thousand of them militants, are to be evacuated under a deal that echoes those struck in Syria between the government and rebels. Those deals have helped Syrian President Bashar Al-Assad recapture rebel areas. Critics say they amount to forcible transfer of populations sympathetic to the opposition.
Hezbollah's role in helping Assad defeat his opponents along the Lebanese, Syrian border has been highlighted in Arsal. Three years ago, the town witnessed one of the most serious spillovers of Syria's six year civil war into Lebanon. Then militants from Islamic State and the Nusra Front, at the time linked to Al-Qaeda, briefly overran the town.
They abducted dozens of Lebanese soldiers and policemen. Nine remained in Islamic State captivity. Their fate is unknown.
