N Korea says it test-fired biggest ICBM, US adds sanctions

North Korea said Friday it test-fired its biggest-yet intercontinental ballistic missile 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 US. Believed to be about 25 meters long, the Hwasong-17 is the North's longest-range weapon and, by some estimates, the world's biggest road-mobile ballistic missile system.
