BEIRUT (Reuters) - A group of Syrian rebels and refugees began to leave a border enclave in Lebanon for Syrian territory on Monday under a deal worked out with Lebanese and Syrian authorities, a TV station affiliated to Hezbollah said.
The departure of rebels from a group called Saraya Ahl al-Sham will leave an Islamic State enclave as the last militant stronghold straddling the border near the Lebanese town of Arsal, which is home to tens of thousands of refugees.
About 300 rebels from the group as well as about 3,000 refugees are to leave Lebanon under the deal that followed an assault by the Lebanese Shi'ite group Hezbollah on insurgent positions last month.
A convoy of 40 buses had left for the Syrian border, al-Manar TV, which is linked to Hezbollah, said. Television footage showed buses very slowly moving through the dry hills of the border area.
The transfer involving Saraya Ahl al-Sham rebels and another one early this month of Nusra Front fighters and refugees, are similar to deals struck within Syria in which Damascus has shuttled rebels and civilians to opposition areas.
On Friday, the Lebanese security official overseeing the arrangements, General Abbas Ibrahim, said a group of civilians would go to Assal al-Ward, an area just across the border from Arsal and held by the Syrian government.
The fighters and their families will go to another part of Syria which he did not identify. Al-Manar said last week they would go to the rebel-held town of al-Ruhaiba in the Eastern Qalamoun region.
Hezbollah is a Lebanese Shi'ite group that has played a big battlefield role in Syria's civil war on the side of President Bashar al-Assad.
Last month it defeated rebels in the insurgent enclaves near the border in Lebanon and forced the hardline Islamist Nusra Front group to leave. About 7,000 refugees departed with them for a rebel-held part of northwest Syria.
The Lebanese army is expected soon to assault the Islamic State pocket in the same area. The United States helps arm the Lebanese army and on Monday delivered eight new armored vehicles, its embassy said.
Defeating the Islamic State pocket would end a period of several years in which armed groups from inside Syria held positions in the hills around Arsal, the most serious spillover of the civil war into Lebanon.
More than 1 million Syrian refugees are sheltering in Lebanon, about a quarter of its total population. Hezbollah has stepped up calls for the Lebanese government to engage directly with Damascus over the return of refugees to Syria.
Syria's opposition has criticized previous evacuations of civilians under ceasefire deals as amounting to the forced transfer of populations, something Damascus denies.
The growing number of evacuation deals for fighters and civilians from besieged rebel areas inside Syria over the past year has helped Assad solidify his hold in several parts of the country.
Lebanon's General Security, the government agency that negotiated Monday's transfer, said all the civilians returning were doing so voluntarily.
