Tensions escalate in Egypt
Protesters hit a riot policeman (C) after surrounding him during clashes in front of the U.S Embassy near Tahrir Square in Cairo November 28, 2012. Hundreds of demonstrators were in Cairo's Tahrir Square for a sixth day on Wednesday to demand that President Mohamed Mursi rescind a decree they say gives him dictatorial powers, and two of Egypt's top courts stopped work in protest.
