Four foreigners have been arrested in the eastern Libyan city of Benghazi on suspicion of being Christian missionaries and printing books about Christianity, a security official said on Saturday.
"They were arrested on Tuesday at a publishing house where they were printing thousands of books that called for conversion to Christianity," security official Hussein Bin Hmeid said.
"Proselytising is forbidden in Libya. We are a 100 percent Muslim country and this kind of action affects our national security."
Hmeid said the government-affiliated security apparatus called the Preventative Security, for which he is a spokesman, had arrested an Egyptian, a South African, a Korean and a Swede who was travelling on a U.S. passport.
