The United States has concluded that North Korea test-launched an intercontinental ballistic missile (ICBM) was a new type of missile that "we've not seen before," a Pentagon spokeswoman said Wednesday in a milestone for Pyongyang's missile program. 

The U.S. military had initially assessed the missile to be only intermediate range. But Reuters reported earlier on Tuesday that, after further reviewing the data, officials later believed it was likely an ICBM, with two different stages. 

"We remain prepared to defend ourselves and our allies and to use the full range of capabilities at our disposal against the growing threat from North Korea," said Pentagon spokeswoman Dana White. "Our commitment to the defense of our allies, the Republic of Korea and Japan, in the face of these threats, remains ironclad."
