A group of foreign journalists arrived in North Korea on Tuesday to cover the dismantling of the country’s nuclear test site later this week. The eight South Korean journalists were excluded because Pyongyang has cut off high-level contact with Seoul to protest an exercise with the US military, AP reports. The North’s media reiterated the protest Tuesday, saying saber-rattling and dialogue don’t mix. Pyongyang is allowing the limited access to the site to publicize its promise to halt underground tests and launches of intercontinental ballistic missiles. North Korea unilaterally announced the moratorium ahead of a summit between its leader Kim Jong-un and US President Donald Trump scheduled for June 12 in Singapore.
