Four foreign Christian workers in Libya have been arrested on suspicion of spreading Christianity and giving out Christian literature in Benghazi, CBN News reports. Police said one of the suspects is a Swedish-American, and the others are from South Africa, Egypt and South Korea. "We are still holding interrogations and will hand them over to the Libyan intelligence authorities in a couple of days," police spokesman Hussein bin Hamid said. The four workers were arrested Tuesday, and police confiscated some 45,000 books in their possession. Another 25,000 reportedly were distributed. Preaching the gospel is against the law in the Muslim-majority nation. Prior to the 2011 revolution that ousted Moammar Gadhafi, Libya was home to approximately 100,000 Christians, but now only a few thousand remain.
