In an unprecedented move, North Korea has released three U.S. prisoners following requests from South Korea and the Trump administration. It is suspected the three Americans were in one of North Korea's most notorious labor camps.
From Business Insider:
Kim Dong-cheol, Kim Sang-deok, and Kim Hak-seong — three US citizens detained in North Korea for years — have been released from a suspected labor camp and given health treatment and ideological education in Pyongyang, according to the Financial Times.
"We heard it through our sources in North Korea late last month. We believe that Mr Trump can take them back on the day of the US-North Korea summit or he can send an envoy to take them back to the US before the summit," said Choi Sung-ryong, who campaigns for the release of detainees in North Korea.
So what this actually means is they've been transferred from a labor camp to a reeducation camp.
