An explosion at a building belonging to a nearby Coptic Christian church killed two Egyptian men and wounded two others on Dec. 30, Reuters reported.

The attackers threw a homemade bomb at an administrative building belonging to the church, according to local police.

“The explosion seems like it was very strong, and I have started making my investigations with Misurata officials,” said Tareq Dahrouj, the Egyptian consul in the city.

It was the first major assault on a Christian site in Libya since the “Arab Spring” began. Christians in Egypt and Syria have faced numerous attacks and upheaval as a result of the Arab Spring revolutions.

Though modern Libya is predominately a Muslim country, Christianity—like Judaism—has been present there since antiquity. Historically, the Egyptian Coptic Christian Church has claimed jurisdiction over ancient regions of Tripolitania and Cyrenaica located in Libya, and today comprises the majority of Christians in Libya along with European immigrants.
