WASHINGTON, April 28 (Reuters) - The U.S. military said on Friday it tracked a North Korean ballistic missile launch but the missile did not leave North Korean territory and did not pose a threat to North America.
Commander Dave Benham, a spokesman for U.S. Pacific Command, said the missile launch took place at 10:33 a.m. Hawaii time (2033 GMT) from near the Pukchang airfield.
U.S. officials, speaking on condition of anonymity, said the missile was probably a medium-range missile known as a KN-17 and appears to have broken up within minutes of taking off. (Reporting by Idrees Ali; Editing by James Dalgleish)
