ISIS claims kidnapping of three African Christians in Libya:
ISIS has kidnapped three African Christians in eastern Libya, the group said, publishing their passport pictures. The men come from Egypt, Nigeria and Ghana, ISIS said in a statement on social media, without elaborating. Ref. Source 8c
With Libya's 97% of the population identifying themselves as Muslim there are hardly Christians present in the country and won't have much chances to spread their influence in the long run. You might encounter small groups of Christians associated with the Coptic Orthodox Church of Alexandria; from Egypt.
