CAIRO, EGYPT – JANUARY 29: Protestors ride an armoured personnel carrier towards the Nile on January 29, 2011 in Cairo, Egypt. Tens of thousands of demonstrators have taken to the streets across Egypt in Cairo, Suez, and Alexandria to call for the resignation of President Hosni Mubarak. Riot police and the Army have been sent into the streets to quell the protests, which so far according to health officials have claimed at least 45 lives and left more than a two-thousand injured. The cabinet has formally resigned, but protesters are seeking a regime change with the resignation of Mubarak. Whilst the Army has deployed tanks and Armoured Personnel Carriers (APCs) to the streets there has been little implementation of them, and soldiers have interacted peacefully with passing marchers. The government has installed a curfew, blockaded access to the Giza pyramids with tanks and APC’s and taken measures to secure museums from looters. (Photo by Peter Macdiarmid/Getty Images)
