North Korea has announced plans to withdraw over 50,000 workers from its shared industrial zone with South Korea. North Korea already cut off access to the Kaesong zone last week amidst a heightened nuclear standoff. Over the weekend, the United States said it would suspend a planned missile test at California’s Vandenberg Air Force Base to avoid further inflaming tensions. Over the weekend, South Korea also accused North Korea of preparing a fourth nuclear test, but the claim was later withdrawn.
