IN FRONT of the campus of the American University in Cairo in Tahrir Square, a garbage collector sweeps debris from five days of running battles downtown between police and protesters which left 10 dead. The violence erupted in the wake of last week's football tragedy in Port Said which killed 74 supporters. Calls have been made for the start of a nationwide civil disobedience campaign beginning Saturday, the first anniversary of the forced departure of Hosni Mubarak as president (photo: AP)
