If you've been following the news, you probably already know that events in Cairo's central Tahrir square have turned very ugly in the last 4 hours.
What you may not know is that the so-called "pro-Mubarak demonstrators" are actually a mixture of government security forces and hired thugs. Pro-democracy demonstrators have shown on Al Jazeera several Egyptian Police identification cards which they took from these so-called "pro-Mubarak" forces. And the army is reported to be standing by observing, but not interfering on either side.
If you want live coverage, I'd suggest that the best is to be found at the YouTube channel of Al Jazeera English. Stop the video at the top of the page, if it starts automatically, and Page Down once. You'll see a live coverage video embedded at the right side, with frequent commentary from a surprisingly informed range of different people. As always, the big difference with AJE is that they have local reporters who actually live there and know who's who in the zoo.
Strange days, my friends, strange days indeed. If you're up for a moment of amusement, imagine how our own President would be pissing his pants if a million of us showed up in Washington DC to protest with such vigor and determination.
