North Korea boasted on Tuesday night that it had conducted a test of a newly developed intercontinental ballistic missile (ICBM) that can carry a large and heavy nuclear warhead, Reuters reported, citing the country's official KCNA news agency.
The report said that the test successfully verified the warhead's atmospheric re-entry.
North Korean leader Kim Jong Un said the successful test completed the country's strategic weapons capability that includes atomic and hydrogen bombs and ICBMs.
He stressed that North Korea will not negotiate with the United States to give up those weapons until Washington abandons its “hostile policy” against the North, KCNA said.
Pyongyang's proclamation came hours after U.S. officials confirmed that in its latest test on Tuesday, North Korea had successfully test-launched an ICBM for the first time.
Experts have in the past warned that North Korea, if left unchecked, is on an "inevitable" path to obtaining an ICBM.
North Korea has declared that it could test-launch an ICBM “at any time” from any location set by its Kim, but until now it was unclear whether any of its recent tests have been of an ICBM.
Meanwhile, South Korea said on Tuesday night that it and the United States had conducted an offensive ballistic missile drill aimed at striking the North's leadership.
