New information on the violence in Tehran today has been slow to emerge. But here, via McClatchy, is a video of one of the shooting victims, who was apparently wounded in the arm. The AP has the latest on the incident that was the focus for the violence:

Later, a group of demonstrators with fuel canisters set a small fire at a compound of a volunteer militia linked to Iran's powerful Revolutionary Guard as the crowd dispersed from the square. As some tried to storm the building, people on the roof could be seen firing directly at the demonstrators at the northern edge of the square, away from the heart of the rally.

An Associated Press photographer saw one person fatally shot and at least two others who appeared to be seriously wounded.

Late Update: We've compiled some of the other compelling videos to come out of iran in recent days.
