CAIRO (AP) — An Egyptian court Saturday sentenced a man to die for the April stabbing death of a Coptic Christian priest in an attack that shocked the Arab world’s most populous nation.

Nehru Tawfiq, 60, was convicted in Alexandria criminal court of murder for killing 56-year-old priest Arsanious Wadid and illegal possession of a knife. His lawyers had argued that the killing was not deliberate. Tawfiq can appeal the verdict.

Wadid was killed at a popular seaside promenade in the Mediterranean city of Alexandria in April.

Investigators found that Tawfiq was an Islamist with an extremist background. During l ast month’s court session he appeared in court in a caged-off section of the room shouting “God is great” in Arabic. He attempted to recite verses from the Quran, the Muslim holy book, before judges ordered him to keep silent.

The attack marked the latest sectarian violence in Egypt. Islamic extremists have repeatedly targeted Christians in recent years, especially after the 2013 military ouster of late Islamist President Mohammed Morsi, an elected but divisive leader, amid mass protests against his rule.
