Egyptian authorities believe a suicide bomber was behind a blast that killed at least 21 people and injured dozens more at a church in Alexandria. The blast hit as Coptic Christians left a New Year's church service, Bloomberg reports. Angry Christians clashed with police and local Muslims after the explosion. A crowd attacked a nearby mosque, which had also been damaged in the blast.
Egyptian President Hosni Mubarak urged the country's Muslims and Christians to stand united against terrorism. Alexandria's governor blamed the blast, Egypt's deadliest terrorist attack since 2006, on al-Qaeda.
