Military police dispersed hundreds of protesters remaining in Cairo’s Tahrir Square from of the biggest demonstrations since Hosni Mubarak was ousted using tasers and batons late on Friday night, a witness said.

Hundreds of thousands of people rallied during the day to pile pressure on the interim military rulers to meet demands including the prosecution of Mubarak.

But after the curfew, set from 2 a.m. to 5 a.m., military police and state security officers surrounded the square, fired shots in the air, used tasers and batons and arrested protesters to break up the crowd, a witness told Reuters by telephone.
