Al-Jazeera Video: Syrian National Council delivers a call to arms

"Syria's opposition has reacted to the Houla massacre -- effectively saying that all bets are off.

Burhan Ghalioun, who heads the Syrian National Council, says if the international community does not intervene with force, then the battle for freedom will begin.

Earlier, Syria's government denied any responsibility for the massacre, which left more than 90 people dead -- a third of them children.
