In North Corea being religious is a sufficient argument to imprison someone. One of the ex-prisoners told the researchers that in the centre where he had been detained, 50-60 per cent of the prisoners had been arrested for participating in Christian meetings in China.

Moreover, Christians are usually sentenced to a longer prison term, their interrogations last more time than others and they are frequently tortured. These tortures aim to make them tell the names of other Christians.

In North Korea, possessing a Bible is enough to be imprisoned. The country is ranked 2nd on Open Doors’ world watch list of persecution.
