Lebanon: What next after GCC blacklisting of Hezbollah? (video)

What could the move by the Gulf Cooperation Council mean for Lebanon's fragile political situation?

Lebanon has long been an arena for competing regional powers.

And as the war in Syria drags on, regional rivals Saudi Arabia and Iran have sought to maintain their influence over the border in Lebanon.

Iran is the patron of the powerful Shia armed group, Hezbollah - a major player in Lebanese politics.

And now, Saudi Arabia, along with its allies in the Gulf Cooperation Council (GCC), have declared Hezbollah a "terrorist" organisation - a move Iran says will undermine regional peace efforts.
