An explosion on Sunday at a building belonging to a Coptic church in western Libya killed two Egyptian men and wounded two others, a military spokesman said.

Attackers threw a homemade bomb at an administration building belonging to the Egyptian Coptic church in Dafniya, close to the western city of Misrata, said Ibrahim Rajab of Misrata military council.

The Egyptian consul in the city, Tareq Dahrouj, said he had visited the church and the building where the two church workers were killed early on Sunday.

"The explosion seems like it was very strong and I have started making my investigations with Misrata officials," he said.

Libya has small communities of Egyptians, Greeks and Italians who account for most of the Christian minority in the predominantly Islamic country.
