Syrian refugees living in the Lebanese town of Arsal say the army will not let them leave without special permission. The town has been a security hotspot since fighters from the al-Qaeda linked group al-Nusra Front and men who pledged allegiance to the Islamic State in Iraq and the Levant (ISIL) took control in August. The army is now back in charge, but refugees say they are still being punished. Al Jazeera's Nicole Johnston reports from Arsal.
