In Egypt thousands of people have converged on Cairo's Tahrir Square to mark the first anniversary of "Friday of Rage," a key day in the popular uprising that ousted President Hosni Mubarak. A year ago Mubarak's security forces fired on protesters who streamed into the square, killing and wounding hundreds. The day ended with a collapse of Mubarak's much-hated security forces.
A year later many are disenchanted and even angry at the ruling military, who protesters accuse of human rights abuses and of reneging on promises of reform. Joining the show is Noel King, reporter in Cairo.
