Thousands of Egyptians continued to demonstrate in Cairo’s Tahrir Square on Wednesday, demanding the military-led government accelerate its transition to civilian rule. Not appeased by a deal struck between the Muslim Brotherhood and the military, protesters attacked the Interior Ministry. Thirty-one people are said to have died at the hands of security forces since the protests began. The United Nations’ human rights chief assailed the Egyptian government for its “clearly excessive use of force” on the protesters. Tim Whewell  of the BBC filed this report on police brutality from Cairo.
