International journalists have touched down in North Korea to cover the dismantling of the country's nuclear test site—but South Korean media, which was scheduled to be there, has been excluded. Eight South Korean journalists who were planning to attend the historic event have been refused access to the country because Pyongyang has cut off high-level contact with Seoul to protest an exercise with the U.S. military. Kim Jong Un is allowing a limited number of foreign journalists to cover the event to publicize its previous promise to halt the country's nuclear tests. But the event comes amid renewed tension between North Korea, South Korea, and the United States—with North Korea threatening to cancel a planned meeting between Kim Jong Un and Donald Trump. The dismantling ceremony is expected to be held in the coming days, depending on the weather.
