No

I simply do not think this claim that Lebanese Hizballah is on the ground in Tehran cracking skulls to be credible. In many domestic conflagrations, outside interferrence is alleged. So while the Iranian regime is trying to claim the Western media and the Americans in general are to blame for the events in Tehran, the "reformists" are alleging that Arabs in the form of Hizballah are some of the thugs delivering beatings to protesters. I simply do not buy this. It sounds like RUMINT of the first degree, and the kind to gain currency because were it true, it would stregthen the claims of legitimacy on one side and weaken the claims of the other.
