“For the eleventh year running, North Korea is the most difficult place on earth to be a Christian. One of the remaining Communist states, it is vehemently opposed to religion of any kind. Christians are classified as hostile and face arrest, detention, torture, even public execution. There is a system of labor camps including the renowned prison No. 15, which reportedly houses 6,000 persecuted Christians alone. Despite the severe oppression, there is a growing underground church movement of an estimated 400,000 Christians." World Watch List – North Korea.
