Pyongyang has sentenced a Korean-American man to 10 years of hard labor for subversion.
A North Korean court handed down the sentence Friday to naturalized U.S. citizen Kim Dong Chul.
Kim confessed last month to attempting to steal North Korean military secrets and asked for mercy when he was paraded in front of the media in Pyongyang in March.
He confessed a week after North Korea sentenced Otto Warmbier, an American student, to 15 years of hard labor for stealing a propaganda banner.
Both Kim and Warmbier confessed to their charges, but observers say both confessions were likely coerced.
Kim and Warmbier's sentences come amid mounting tensions following North Korea's launching of nuclear weapons tests and long-range rockets tests. Washington, Seoul and Tokyo have increased their defense readiness postures in response to the tests. U.S. and South Korean forces have conducted joint annual military exercises.
