1. North Korea
It is impossible to know precisely how many Christians live in North Korea: they are considered enemies of the state because they believe in an authority greater than the Kims, so must keep their religion completely secret – often from one another. It is estimated, however, that there are between 200,000 and 400,000 Christians there, of whom 50,000 to 70,000 are imprisoned in labour camps.
2. Afghanistan
As in North Korea, Afghan Christians must keep their religion utterly secret. Islam is seen as intrinsic to Afghan identity; it is illegal for any Afghan to leave that faith. Those found to have done so can be confined to a mental hospital, beaten or even killed. It is estimated that there are thousands of Christians living in secret.
