The al-Mujahidin organization, associated with al-Qaeda, claimed responsibility for the attack on the church in Alexandra which left 21 people dead.
"Every devout Muslim must demonstrate solidarity with the attack on the church at a time it was full of people celebrating Christmas," the organization said in a notice. Prime Minister Benjamin Netanyahu spoke with Egyptian President Hosni Mubarak to express his horror at the attack. (Roee Nahmias and Attila Somfalvi)
