People walk past a TV news showing an image of North Korean leader Kim Jong Un while reporting North Korea's missile test which landed in the waters of Japan's economic zone (EEZ) in Tokyo Tuesday, July 4, 2017. North Korea claimed to have tested its first intercontinental ballistic missile in a launch Tuesday, a potential game-changing development in its push to militarily challenge Washington — but a declaration that conflicts with earlier South Korean and U.S. assessments that it had an intermediate range.

North Korea delighted in the international furor created by its first launch of an intercontinental ballistic missile, vowing Wednesday to never give up its missiles or nuclear weapons and to keep sending Washington more "gift packages" of weapons tests.
