An intercontinental ballistic missile fired by North Korea on Friday traveled about 1000 km from Mupyong-ni before splashing down in the Sea of Japan, Pentagon officials said.

The U.S. Department of Defense detected the launch around 10:40 a.m. EDT. Pentagon spokesman Navy Capt. Jeff Davis said in a statement that officials were assessing the launch Friday.

"The North American Aerospace Defense Command determined the missile launch from North Korea did not pose a threat to North America," Davis said. "Our commitment to the defense of our allies, including the Republic of Korea and Japan, in the face of these threats, remain ironclad. We remain prepared to defend ourselves and our allies from any attack or provocation."
