North Korea claimed Tuesday that it test-launched its first intercontinental ballistic missile.
The claim contradicts earlier reports from U.S. and South Korean officials who earlier said the launch was an intermediate-range missile.
The North has previously conducted satellite launches that critics say were disguised tests of its long-range missile technology. But a test-launch of an intercontinental ballistic missile, if confirmed, would be considered a game-changer by countries looking to check North Korea’s push for a nuclear-armed missile that can reach anywhere in the United States.
The test still may be the North’s most successful yet; a weapon analyst says missile could be powerful enough to reach Alaska.
