WASHINGTON, July 22 (UPI) -- A U.S. research group said it found early evidence of a secret North Korean facility used for uranium enrichment for nuclear weapons, a discovery that may be critical in any future nuclear negotiations with North Korea.
The Washington, D.C.,-based Institute for Science and International Security said the suspected site is believed to be located in an underground factory that makes airplane components, about 29 miles west of the Yongbyon nuclear facility. It was discovered using satellite imagery.
