The BBC, which has a reporter there, has reasonable coverage:http://www.bbc.co.uk/news/world-africa-12195025

Note the reporter's comment on the prospects:
The protesters have put their bodies on the line, and many people have been killed. Tonight, they ignored the curfew to celebrate on the streets. At the end of a dramatic day, President Ben Ali fled, no longer able to hold back the growing tide of public discontent and anger with his regime. Now, the protesters will want to see the fruits of their demonstrations. They won't settle for meagre reform, they won't settle for the same elite remaining in power. They're very happy that the president has gone, but they don't like the regime that surrounded him, and they'll want his cronies out as well.
What I noticed watching the latest newsreel is that those on the streets were not the youth.
