The northern Syrian province of Idlib had become a stronghold of the armed opposition, before the army launched an assault to retake control of the area.
Among the fighters are army defectors, engineers, teachers, doctors, lawyers and university students. They say most of their weapons are stolen or bought from the regular Syrian army.
