A Coptic priest was shot dead Saturday on al-Sentral Street in the North Sinai neighbourhood of al-Masaeed.
Gunmen shot dead a Coptic Christian priest in Egypt's lawless region in the third recorded instance of sectarian violence against Christians since President Mohamed Morsy was ousted.
The shooting in the coastal city of Arish was one of several attacks believed to be by Islamist insurgents that included firing at four military checkpoints in the region, the sources said.
A security source said Saturday that gunmen riding a motorcycle shot dead the priest, named as 39-year-old Mena Aboud Sharoben, who lived in Arish.
Morsy's Muslim Brotherhood has fiercely criticized Coptic Pope Tawadros II, the spiritual leader of Egypt's eight million Christians, for giving his blessing to the removal of the president and attending the announcement by armed forces commander General Abdel Fattah al-Sisi suspending the constitution.
