Since mainstream media in the U.S. is sketchy at best (rumors of some outlets not being able to spot Egypt on a map), we've come to rely on sources overseas for the latest news and developments in this fast-paced story.
This report, via the BBC World Service Newshour program, comes this morning. No doubt there have been additional developments since then. I would urge you to check out the other outlets, most all of them (with the exception of Radio Cairo who are suspiciously down the past couple of days) are streaming audio in order to keep up to date.
In the meantime, here is the BBC on the ground in Cairo.
