Protesters against Egypt's President Mohamed Mursi rest in front of a tent named ''Revolution Party'' at Tahrir Square in Cairo December 17, 2012. Egypt's opposition called for nationwide protests against a constitution backed by Mursi, after a vote exposed deep divisions that could undermine his efforts to build consensus for tough economic measures.
