North Korea heralded the successful development of a new "high-thrust engine" during a visit to the country's rocket test site by leader Kim Jong Un, the reclusive nation's state media said Sunday.
Kim observed the test of the indigenously built high-powered engine at the North's Sohae satellite facility in Dongchang-ri on Saturday, according to the Korean Central News Agency.
The facility is near the site where the isolated country launched four extended-range Scud missiles earlier this month as part of a practice exercise aimed at striking U.S. military bases in Japan.
