Four foreigners, including one South Korean, have been arrested in Libya for distributing Christian books and propagating a religion other than Islam, Al Jazeera reported Saturday.

Libyan police said they arrested a South Korean, an Egyptian, a South African and a Swede in Benghazi on Feb. 12, and confiscated about 45,000 Christian books in their possession. Those targeted are suspected of printing and distributing some 25,000 books over a considerable period of time.

Ninety-seven percent of Libyans are Sunni Muslims. The Libyan government bans missionary work for religions other than Islam.
