North Korea test fires its biggest ICBM yet, it could apparently reach the entire U.S.

North Korea said Friday it test-fired its biggest-yet intercontinental ballistic missile (ICBM) under the orders of leader Kim Jong Un, who vowed to expand the North's "nuclear war deterrent" while preparing for a "long-standing confrontation" with the United States.

The report by North Korean state media came a day after the militaries of South Korea and Japan said they detected the North launching an ICBM in its first long-range test since 2017.

The Hwasong-17, which was fired at a high angle to avoid the territorial waters of neighbors, reached a maximum altitude of 3,880 miles and traveled 680 miles during a 67-minute flight before landing in waters between North Korea and Japan, Pyongyang's official Korean Central News Agency said.
