Islamic State fighters and their families who had been inside an IS enclave on the Lebanon-Syria border reached an exchange point in eastern Syria on Tuesday from where they will head to IS-held territory.
The transfer under Syrian military escort was agreed under a ceasefire deal. The convoy of buses and ambulances left the border region on Monday after a ceasefire took effect on Sunday.
The deal ended a week-long offensive with the Lebanese army on one front and Hezbollah with the Syrian army on the other against Islamic State's mountainous enclave straddling the Lebanon-Syria border.
