Egyptian military police fight protesters in square
Egyptian military police in riot gear have stormed Tahrir Square in Cairo to try to seize control from protesters who had set up camp there.
Demonstrators fled as officers fired tear gas and beat them with truncheons.
The violent clashes between the security forces and protesters have lasted two days in Cairo and other cities.
