UNITED NATIONS (AP) — North Korea has continued to develop its nuclear and ballistic missile programs including its capability to produce nuclear device components in violation of U.N. Security Council resolutions, U.N. experts said in a new report. The panel of experts said in the executive summary of the report obtained Saturday night by The Associated Press that there was “a marked acceleration” of Pyongyang’s testing and demonstration of new short-range and possibly medium-range missiles through January, “incorporating both ballistic and guidance technologies and using both solid and liquid propellants.” “New technologies tested included a possible hypersonic guiding warhead and a maneuverable re-entry vehicle,” the panel said. North Korea also demonstrated “increased capabilities for rapid deployment, wide mobility (including at sea), and improved resilience of its missile forces.” The experts said North Korea “continued to seek material, technology and know-how for these programs overseas, including through cyber means and joint scientific research.”
