With western news organizations banished from covering street demonstrations in Iran, the role of "citizen journalists" has become essential.

CNN's iReport has been getting many uploads about the Iran crisis, about 4,600 over the past week, including 1,600 last weekend alone. While these user-generated videos go up on the site without filtering, CNN producers vet these videos for use on the air and on CNN.com

The network has pulled 150 user generated clips from iReport, we have been told by a CNN spokesperson.

Uploaders in Iran need to be enterprising as the Iranian government has blocked CNN.com since last week.

Below is a clip about CNN's Iran news gathering operation Atlanta. 

Here is a phone interview with a 19 year old in Tehran who describes the beatings of women by militia.
