North Korea has executed five officials for their part in the failed second summit between President Trump and North Korean leader Kim Yong-un according to a South Korean newspaper.
Kim Hyok Chol, North Korea's special envoy to the U.S., was executed by firing squad in March for being "won over by the American imperialists to betray the supreme leader", according to the Chosun Ilbo.
The paper also claimed that four other North Korean Foreign Ministry officials were executed that same month because of the breakdown of the February summit in Hanoi, Vietnam, but did not provide details.
Seoul's spy service said it could not confirm the report, while the presidential Blue House said that "it's inappropriate to make hasty judgments or comments."
Mike Pompeo, the U.S. Secretary of State, told reporters in Berlin that he had seen the reports and the U.S. was "doing our best to check it out."
Trump’s much-anticipated summit with Kim ended abruptly and without the two leaders signing any agreements over nuclear disarmament.
Top Kim aide Kim Yong Chol is reportedly undergoing hard labor for his role in the breakdown.
Kim Yong Chol has been North Korea’s top nuclear negotiator and the counterpart of U.S. Secretary of State Mike Pompeo since Kim entered nuclear talks with the U.S. early last year.
