Inside Syria - The hand of Hezbollah in Syria

Are there any truth to the reports that Lebanon's Hezbollah are supporting the Syrian regime in quelling the opposition? Hazem Sika is joined by Abu Rami, a spokesman of the Syrian Revolution General Commission; Reuel Marc Gerecht, a senior fellow at the Foundation for the Defence of Democracy. He is also a former Middle East specialist at the CIA; and Kamel Wazne, a political analyst and a professor at the Lebanese University. Wazne is also the director and founder of the Centre for American Strategic Studies in Beirut.
