From Christianity Today, May 2005, p. 21
"For the third year in a row, NORTH KOREA has been named the worst persecutor of Christians, according to OPEN DOORS INTERNATIONAL's 'World Watch List.' North Korea is followed by Saudi Arabia, Vietnam, Laos, Iran, the Maldives, Bhutan, China, and Afghanistan."
Note: tens of thousands of believers are in North Korean prison camps.
