BRENDAN TREMBATH: Our correspondent Ben Knight is in the Egyptian capital, Cairo and joins us now.

What's been the scene since you arrived there?

BEN KNIGHT: Well Brendan it's been very still. We arrived late last night, in fact not long after Mohamed ElBaradei arrived in Egypt and the streets were very quiet and you'd have to say not a particularly strong police presence. And I'm standing very, very close to the main square of Cairo this morning. It's quarter past eight in the morning, a very beautiful clear morning and the street's quite quiet.

But what we're seeing is that the trucks are starting to roll in, the trucks carrying police officers and also riot policemen. And as I was walking around just a short time ago a gentleman asked me where I was staying? I said I was staying at a hotel nearby and he said do not go outside after midday.

Er, I thought 100 people were dead, OP? I thought they were filling the streets with burning gas to keep them at bay?

OP, please explain.
