Kim Jong Un supervises test launch of North Korea's new solid-fuel long-range ballistic missile for first time

North Korea said on Friday it flight-tested a solid-fuel intercontinental ballistic missile for the first time, a possible breakthrough in its efforts to acquire a more powerful, harder-to-detect weapon targeting the continental United States. Thursday's test did not appear to demonstrate the weapon's full capacity, and it remains unclear how far North Korea has come in mastering technologies to ensure the warhead would withstand atmospheric reentry and accurately strike targets.
