The U.S. Strategic Command says it detected and tracked what it assessed was a medium- or intermediate-range ballistic missile test-fired by North Korea.

It says it did not pose a threat to North America.

The command said the launch occurred near the northwestern city of Kusong.

North Korean leader Kim Jong Un warned in his New Year’s address that his country was ready to test its first intercontinental ballistic missile, which could threaten the U.S. mainland.
