Lebanese Red Cross delivered 4 bodies for Saraya Ahl al-Sham group were killed in fighting with Hezbollah due to a ceasefire reached last week at the Syrian-Lebanon border, spokesman told Ammar Johmani on Tuesday.
Omar al-Sheikh said one of the bodies belongs to a fighter killed by Hezbollah two years ago in mountainous Juroud Arsal border region.
Saraya Ahl al-Sham is due to leave to eastern Qalamoun region with 3600 refugees and families of the fighters. Lebanon's Hezbollah militia and jihadist militants on Sunday started exchanging the bodies of fighters.
Last week, Lebanese militia Hezbollah took most of the mountainous border area, called Jroud Arsal, in a joint offensive with the Syrian army to drive Nusra Front militants from the area, which straddles the border.
About 9,000 people are expected to be transferred and go to Idlib province, a Hezbollah media unit said.
Meanwhile, the transfer of thousands of Tahrir al-Sham fighters and refugees to northern Idlib province stalled for a second day on Tuesday because Beirut rejected demands made by the militants, a Lebanese official told Reuters.
A security source said those demands included the release of prisoners held in a Lebanese jail and safe passage out of the country for some people wanted by the Lebanese state including militants in the Ain el-Hilweh Palestinian refugee camp.
The source also said on Tuesday evening that the coming hours would be "decisive".
Lebanese television station al-Mayadeen said Nusra Front militants were demanding the release of a fifth prisoner being held by Beirut and accused of killing Lebanese soldiers. Beirut and Hezbollah had refused, Al-Mayadeen reported, citing sources.
Lebanon hosts nearly 1.5 million refugees - about a quarter of its population. Most live in severe poverty and several thousand are in makeshift camps east of Arsal in a barren mountainous region.
The multi-sided Syrian conflict has killed hundreds of thousands of people and driven at least 11 million from their homes - about half Syria's pre-war population.
