Kim Jong-un has sent a special thank you message to builders who have been working on a tourism project in a seaside resort, a state newspaper claims.
The report in Rodong Sinmun comes amid wild speculation over the health of the North Korean leader, who is said to have undergone heart surgery on April 12.
State media reported that Kim had thanked workers on the project in the city of Wonsan, where a train believed to be his has been spotted in satellite images amid unverified reports that he is either dead, in a vegetative state or "alive and well".
Kim's whereabouts and the status of his health remain a mystery as he has not been seen in state media reports since April 11, the day before he reportedly had the operation.
