If true, another sign of how desperate the regime is. A reader writes:

Just got off the phone with my dad. He leaves in northern Tehran, off Afrika Blvd.

He said that most iranians believe that a lot of the "commandos" on the bikes are Hezbollah arabs brought in to do to the citizens what a Persian cop would refuse to do. Accordingly when the protesters knock one of the biker thugs off they are being particularly brutal, believing that the rider is Arab.

Bank storefronts have been smashed all over northern Tehran. Mousavi, Khatami and Rafsanjani are allegedly meeting at Mousavi's house (who is under house arrest) and are planning their next move. People there are waiting for further instructions from Mousavi. In my dad's neighborhood BBC Persia and Voice of America have been knocked off the satellite but not in all parts. Sorry this is rambling I'm getting constant calls from Tehran. Will speak to my father again in two hours and will let you know anything new.
