AMANPOUR (voice-over): It's a strange mix of emotions. Here, Mubarak's people embrace the soldiers. And down the road at the entrance to Liberation Square, anti-Mubarak protesters work with the military, as well. Volunteers help with security. They check IDs as people filed into the square for what organizers hoped would grow to a million marchers.
(on-screen): Why are women and men being separated?
(UNKNOWN): Because this is personal check.
AMANPOUR: I get it.
(UNKNOWN): Like in airports.
AMANPOUR: I get it. OK. And what are you checking for?
AMANPOUR: Even though the army is out in force, even though the government tried to stop them by closing down the train station, sealing off some the roads, this has been nonstop all day. It is certainly the biggest protest that this city has seen since they began a week ago.
(voice-over): The mood was jubilant. Egyptians for the first time were able to see life beyond the shadow of President Mubarak.
(on-screen): Do you think he did anything good for Egypt?
(UNKNOWN): Yes, I did. He's done a lot of good for Egypt. He's a tragic figure, in a way. He started out, you know, honorable, good, and well, but then, in the end, the concentration of power, his grip on power, his obsession with it is bringing this country down.
AMANPOUR (voice-over): And that night, the protesters came a step closer to getting what they wanted when President Mubarak announced that he would not run in the next election, a victory, but here it still wasn't enough.
And by morning, it became only too clear that the system would not go down without a fight. It started with a group of pro-Mubarak demonstrators shouting angrily, "He's not leaving," making their way towards the anti-Mubarak protesters assembled in Liberation Square. They streamed in on foot along the Nile and even floated down it. We were standing on a nearby rooftop watching as their numbers exploded.
And suddenly this almost medieval sight: men riding horses and camels galloping in at breakneck speeds, charging the crowd and cracking their whips. Soon, this square was a battleground, and it raged on for hours. Rocks were hurled from both sides. There were bloody beatings and Molotov cocktails tossed into the crowd. Some were likely genuine Mubarak supporters, but others merely thugs sent in as agitators.
People began ripping up pavement and turning it into weapons. At least three were killed and hundreds more were injured, a mosque turned into a field hospital.
We went back to the square and quickly found ourselves surrounded by an angry mob of pro-Mubarak supporters.
(UNKNOWN): We hate Americans (inaudible) OK, go (inaudible)
AMANPOUR (on-screen): You want us to go?
(UNKNOWN): Yes, I want you go to from here.
(UNKNOWN): Because we are hate you. We hate Americans.
AMANPOUR: You hate us?
(UNKNOWN): Yes, I hate you. And I hate you.
AMANPOUR: Why do you hate us?
(UNKNOWN): You are not good person (ph). Go to any (inaudible) you are not with us. You are not with us.
AMANPOUR: OK. All right.
(voice-over): They kicked in the car doors and broke our windshields as we drove off.
(on-screen): They hit the car with their fists over and over again and threw a rock through the front window. The glass is shattered all over our driver.
Are you OK? Did they hurt you? Wagi (ph), did they hit you?
(UNKNOWN): No. No.
