Image: A prison camp located in Tumen, a Chinese border city with North Korea, where defectors are allegedly held before being repatriated to North Korea. This photo was taken by a JoongAng Ilbo photographer in September 2011. It’s the same camp shown in a photo distributed by an activist in Seoul yesterday. By Kim Kyung-bin. In a flat rejection of South Korea’s plea to stop the repatriation of North Korean defectors, China sent home some recently captured refugees, sources told the JoongAng Ilbo.
