Even as the authorities clamp down on the opposition, and foreign news outlets are forced out of the country, information continues to flow out of the country on blogs, YouTube, and, most of all, Twitter.

You can follow the unfiltered Twitter coverage at #irancoverage, but as many news outlets warn, it's hard to tell the gossip from the reliable news. If you're looking for a more manageable approach, here are some of the more high-profile new media sources:

Photo blogging:

Tehran24 is a blog posting pictures and videos from the streets of Tehran -- including some dramatic pictures of Iranians setting protest fires and running away from police forces.

More photos are available on Flickr and on Picasa.
