Protesters shout slogans against the military and interior ministry, while gesturing with four fingers in front of riot police after blocking Al Nasr street in front of Al-Azhar University headquarters at Cairo’s Nasr City district, November 19, 2013. Police fired teargas to disperse a crowd of several hundred people in Cairo’s Tahrir Square on Tuesday, two years after 42 were killed in protests against military rule. The “Rabaa” or “four” gesture is in reference to the police clearing of the Rabaa al-Adawiya protest camp on August 14. REUTERS/Amr Abdallah Dalsh (EGYPT – Tags: POLITICS CIVIL UNREST)
