A video uploaded by Syrian rebel forces Thursday shows intense fighting for every meter of territory in Al Qahataniya, in the Quneitra region just east of the Israeli-Syrian Golan Heights border.

The UN confirmed Thursday that 43 UN peacekeepers from Fiji had been taken hostage at Quneitra and that it is doing all it can to secure their release, reports AFP.

"Forty-three peacekeepers from the United Nations Disengagement Observer Force (UNDOF) were detained early this morning by an armed group in the vicinity of Al Qunaytirah (Quneitra)," the UN said in a statement.

The "armed group" of Syrian rebels reportedly includes fighters from the Al Qaeda-linked Al-Nusra Front. Indeed, pictures from the border show rebel forces setting black Al Qaeda flags on the Syrian side of the barrier.
