A Youtube video shows a group of rebels including fighters from Al Qaeda affiliate al-Nusra Front taking over the Quneitra border crossing on the Syrian side of the border with Israel after a battle with Assad regime forces. A fighter:
We are Al-Nusra fighters. We’ve just liberated the Syrian-Zionist crossing of Quneitra
In the footage, a black al-Nusra banner is seen flying in place of a Syrian flag in the border town, which is visibly damaged by the battle.
