A North Korean official who was reported to be in a labour camp has appeared at a concert alongside Kim Jong-un, according to North Korean state media.
Last Friday, Kim Yong-chol was widely reported to have been sent to a prison camp as punishment.
But on Sunday, North Korean media showed him at a musical performance together with other officials.
Kim Yong-chol, a former spymaster, has been described as the North Korean leader’s right-hand man.
He travelled to the US in January to prepare for the second summit meeting between Mr Kim and President Trump, which was held in Vietnam.
Reports of purges or the executions of high-ranking North Koreans who have fallen from favour are difficult to verify, and often prove inaccurate.
The reports on Friday also said that Kim Hyok-chol, the former North Korean envoy to the US, was executed at an airport in Pyongyang. He was another key figure in talks ahead of the US-North Korea summit held in Hanoi in February.
Kim Hyok-chol was not among the attendees listed for Sunday’s event, but state media have not yet reported any execution or punishment so his whereabouts remain unclear.
