A Red Cross ambulance carried the coffin of Abbas Khan, an orthopedic surgeon from south London who had gone to Syria to work in rebel-held Aleppo, across the border into Lebanon.
Khan’s family say they do not believe the explanation of his death given by Syrian authorities - that he committed suicide by hanging, days before his scheduled release.
His mother Fatima Khan went to visit him in prison in Damascus on Monday but was told he had died.
She accused the intelligence services of President Bashar al-Assad of killing her son.
‘They murdered my baby, they killed my baby, this is murder,’ she told reporters in Beirut.
