The Latest: Expert: Chicago, LA in range of North Korea ICBM

The Latest on North Korea's launch of its second intercontinental ballistic missile (all times local):

3:20 a.m.

A private analyst who closely watches North Korea's nuclear and ballistic missile programs says that if reports about the country's second intercontinental ballistic missile launch are accurate, the projectile would be powerful enough to reach a wide swath of the United States.

North Korea launched the missile at a steep trajectory late Friday night. Japanese officials said it flew about five minutes longer than the North's first ICBM, launched July 4.

David Wright, a physicist and co-director of the global security program at the Union of Concerned Scientists, said in Washington on Friday that if reports of the missile's maximum altitude and flight time are correct, it would have a theoretical range of at least 10,400 kilometers (about 6,500 miles). That means it could have reached Los Angeles, Denver and Chicago.
