North Korea's new missile sparks fear and confusion in Japan.

North Korea has successfully tested a new type of intercontinental ballistic missile (ICBM) that uses solid fuel, making it quicker to launch and harder to detect. The missile, named Hwasong-18, is a major milestone for the nation's military and will greatly strengthen its already formidable nuclear arsenal. Experts say the missile's development shows that US efforts to prevent North Korea from developing advanced nuclear technology have largely failed. The test took place on Thursday morning, local time, and caused a brief alert on the Japanese island of Hokkaido.
