Former Egyptian foreign minister Amr Moussa leads one of many anti-Morsi protest marches heading to Tahrir square Tuesday, Nov. 27, 2012. At least a hundred thousand Egyptians have been protesting today in a central square in Cairo, challenging the decision by Egypt's president to grant himself sweeping new powers. The protesters, waving Egyptian flags and chanting slogans against President Mohammed Morsi, joined hundreds of others who had been camping out in the square since Friday, demanding that the decrees be revoked.
