Sonia Verma of the Globe and Mail is tweeting from the scene. Her most recent tweets, blocked into paragraphs:

Pro mubarak supporters jumping onto tanks. I am watching one have a very long talk with a soldier. Standing at one of the exits to tahrir. pro mubarak supporters standing on army tanks.

Hundreds of pro dem protesters pouring out of tahrir as things heat up. Groups of men mobilizing, arming themselves with bricks and sticks. Crowds pushing to get out of tahrir square. People saying they will use bricks as weapons. People digging up bricks in tarhir square. Everyone on edge today. Very different vibe than yesterday.

The Guardian:

 Very ominous information coming out of Cairo, with reports of gunfire. Al Jazeera suggests they might be warning shots to keep people away from the museum, which is being defended by a number of military vehicles.

Mackey flags the reaction of an Egyptian blogger:

In a biting, angry and harrowing commentary on the clashes unfolding in Cairo on Wednesday, the Egyptian blogger who writes as Sandmonkey has called the appearance of regime supporters on Cairo's streets, igniting violent clashes, a ploy by President Hosni Mubarak to create chaos and justify his continued rule.

The BBC:

People are using loudspeakers to appeal for calm in Tahrir Square. The army also appears to have parked several lorries across one road near the Egyptian Museum to separate the pro- and anti-government demonstrators. They are still, however, throwing stones at each other. Soldiers have their weapons drawn and one is reportedly firing into the air. The BBC's Ian Pannell says the situation is still very volatile and very dangerous.
