Revolutionary rumors in Iran

I don't know the reliability of this report (linked by The Corner), but there may be some activity brewing in Iran:

Reports over the past 24 - 48 hours via several important information services such as SMCCDI, Peykeiran, Zagros and direct email reports and phone calls from Iranian citizens is beginning to shine light on what at this time looks to becountry-wide fighting and quickly escalating into what could potentially become a freedom revolution.

Several independent citizen sources have reported the formation of significant crowds throughout the country, and have heard many loud explosions and gun shots, including in the cities of Tehran, Esfahan, and Shiraz.

SMCCDI stands for Student Movement Coordination Committee for Democracy in Iran.

Update: Apparently the crowds were involved in peaceful demonstrations, perhaps of Zoroasterian origin.
