Protesters mass in Tahrir Square

Tens of thousands of protesters chanting “Leave, leave!” are rapidly filling up Cairo’s Tahrir Square today in what promises to be a massive demonstration aiming to force Egypt’s ruling military council to yield power.

The rally is dubbed by organisers as “The Last Chance Million-Man Protest”, and comes the day after the military offered an apology for the killing of nearly 40 protesters in clashes on side streets near Tahrir over the last week.
