An opposition supporter lifts a placard at the front line near Tahrir Square in Cairo February 7, 2011. Protesters, barricaded in a tent camp in Tahrir Square in the heart of Cairo, have vowed to stay until President Hosni Mubarak quits and hope to take their campaign to the streets with more mass demonstrations on Tuesday and Friday. The placard reads, “Thanks Egypt youth” (top) and “we will not leave till we get the 70 billion dollars”. The word “Facebook” is written in English.
