Kim Jong-un has been pictured visiting a school just hours after reports claimed he executed five top diplomats over the failed summit with Donald Trump.
South Korean media claimed yesterday that Kim Hyok Chol and four others were executed by firing squad for betraying the supreme leader after being won over by the United States.
Kim Hyok Chol was the Norths counterpart of US special representative Stephen Biegun in the run-up to the Hanoi summit in February and laid much of the groundwork for the historic meeting.
Two other officials, Kim Yong-chol and Kim Song-hye, have reportedly been imprisoned along with Kim Jong-uns interpreter, who reportedly made a mistake.
North Korean state media have yet to confirm the alleged political purge, but instead released images of the beaming despot posing with crying children.
The North Korean leader paid a visit to the 250-mile Journey for Learning Schoolchildrens Palace in Jagang province, close to the Chinese border.
A number of students seemed to be overcome with emotion, and were pictured bursting into tears in his presence.
After his school visit, he then gave the February 8 General Machine Factory field guidance.
The centre has been used to build ballistic missiles, and Kim Jong-un reportedly ordered a higher modernisation plan to be put in place for the factory.
Since the Hanoi nuclear summit ended in failure, North Korea has again tested weapons.
Seouls spy service said it could not confirm Fridays report, while US Secretary of State Mike Pompeo said that he had seen the report and was doing his best to check it out.
