North Korea has not tested a nuclear weapon or its long-range intercontinental ballistic missiles (ICBMs) since 2017, but has suggested in could resume such tests because talks with the United States are stalled.
Its latest flurry of missile launches could be groundwork for a return to ICBM and nuclear bomb tests this year, the U.S. Directorate of National Intelligence (DNI) said in its annual Worldwide Threat Assessment released this week.
A satellite launched into orbit would be the first since 2016.
Recent sub-orbital launches, which likely used road-mobile medium-range ballistic missiles, appeared designed to "pop the key components of an imagery reconnaissance satellite up to operational altitudes for a few minutes of testing", 38 North, a U.S.-based monitoring group, said in a report.
