North Korea said on Friday that it had successfully tested a powerful new missile engine this week, indicating that the country was working to build a solid-fuel intercontinental ballistic missile, a new weapon that its leader, Kim Jong-un, wanted to add to his growing nuclear arsenal.
With Mr. Kim watching, engineers from North Korea’s Academy of Defense Science conducted a ground test of a “high-thrust solid-fuel motor” on Thursday at the Sohae Satellite Launching Groun, in Tongchang-ri, in northwestern North Korea, the country’s official Korean Central News Agency reported on Friday.
