From what I was able to gather from Fox, al Jazeera showed Arafat's speech to their worldwide audience, but it was blocked inside Lebanon (or just Beruit, or just where ever the meeting place of the Arab League is). The Pals stomped out, everyone's fighting with one another, Mubarak is a no-show, as well as the King of Jordan, and the Arab League "summit" is starting out to be quite the disaster.
Allow me a minute while I snicker.

The Arab delegates were likely partying in Beirut with the good booze and the expensive whores. When it came summit time they were too out of it to get their act together. Hence the chaos and contention as the Arab "summit" turned into a rump caucus.
