WASHINGTON — North Korea is continuing work on its ballistic missile program, U.S. officials briefed on recent intelligence tell NBC News, confirming the gist of a private report Monday detailing recent improvements made at undeclared military sites.
A separate analysis by the Middlebury Institute of International Studies, provided exclusively to NBC News, describes a secret military base deep in North Korea’s interior that analysts believe could house missiles capable of reaching the United States.
American defense officials stressed that they consider it a positive development that North Korea has not conducted a nuclear test since September 2017.
“North Korea has continued its ballistic missile program at a number of bases but it’s significant that they have not tested one in nearly a year,” one official said. “We need to give the diplomats time and space to work.”
