Egyptians raise their shoes in a sign of rejection of presidential runoff candidate Ahmed Shafiq, an ex-prime minister under the ousted regime of Hosni Mubarak, during a protest in Cairo's central Tahrir Square on June 1. Earlier this week, attackers set fire to Shafiq's headquarters following the announcement that he was to face the Muslim Brotherhood candidate Mohammed Mursi in the second round of Egypt's presidential election on June 16-17.
