We just got back to the hotel after trying to film on the bridge into Tahrir Square.
An angry mob surrounded us and chased us into the car shouting that they hate America. They kicked in the car doors and broke our windshield as we drove away.
The worst clashes since Friday erupted today in Cairo with pro- and anti-Mubarak mobs facing off in Liberation Square. Shots have been fired and there have been reports of injuries.
Tensions have erupted on a day of some improvements, such as the Internet being restored and curfew hours being shortened.
In Tahrir Square, protestors say two things. Some say that President Hosni Mubarak's announcement Tuesday night that he will not seek reelection is not enough and that he has got to go now. Others say that although they have protested against him, they want him to leave in an orderly fashion, with dignity.
A majority, it seems, are concerned that if he leaves quickly, the economy and institutions could collapse, resulting in an explosion of crime and violence.
And so the overwhelming feeling on the street is one of fear, of how this is now going to go. If Mubarak leaves precipitously, there could be real chaos.
