There was many fires at the Rabaa camp as the police moved to disperse the MB camp. There are pictures that show some people may have burned to death.

Sometimes tear gas can cause fires.

But the police made a odd claim, that the Muslim Brotherhood had set the fire themselves.

That would seem a very odd claim.

Except, that here on video you can see MB, building the fires, seemingly with the intent to use the fire as a defensive line against the police.
