Worshippers at three Christian churches came under attack from knife-wielding assailants during Mass Friday. Police confirmed one worshipper died and more than a dozen injured in the simultaneous attacks in the northern city of Alexandria.
Police were searching for three men, one in each attack, the AP reported.
Hundreds of Christians gathered in angry protest outside the Coptic Christian churches, and witnesses said clashes erupted between Christians and Muslims.
Initial police reports said a total of 17 people were wounded.
