An Egyptian Christian holds a banner next to a Muslim holding a Koran as they protest against what they say is the failure of authorities to protect them, in Cairo January 3, 2011 after a suspected suicide bomber killed 21 people and wounded 97 outside a Coptic church in the Nile delta city of Alexandria during a New Year’s midnight service. Egypt is screening people who arrived recently from countries where al-Qaeda is known to recruit after early findings suggested the militant network was behind the bombing, security sources said. The banner reads, “No to terrorism”. Picture taken January 3, 2011. REUTERS/Mohamed Abd El Ghany (EGYPT – Tags: RELIGION CIVIL UNREST POLITICS)
