Video Shows Iranian Paramilitaries Shooting at Protesters

Channel 4: Shots have been fired during a huge rally in support of the defeated presidential candidate Mir Hossein Mousavi. Witnesses say people ran from the scene in panic, as several armed men opened fire. And there are also reports of gunfire in three areas of northern Tehran. Tens of thousands of people had gathered in central Tehran to back Mousavi's call for new elections after the hard-line president Mahmoud Ahmadinejad was swept back to power.
