Army tanks clear some pro-Mubarak forces in square

Four army tanks have moved into positions protecting the anti-government protest camp in Cairo's Tahrir Square hours after automatic weapons fire pounded the demonstrators before dawn on Thursday.
One tank moved onto a bridge overlooking the square and pushed out young men who had been throwing stones at the anti-government protesters. Four other tanks took up a position between the pro-Mubarak forces and the largest group of anti-government demonstrations at the north end of the square near the Egyptian Museum.
