North Korea's Kim calls ICBM test a 'clear signal' to the U.S.

North Korea's test of a solid-fuel intercontinental ballistic missile (ICBM) should serve as a warning to the United States and its allies, ruler Kim Jong Un said, according to state-run media on Tuesday.

The launch of the Hwasong-18 on Monday sent a "clear signal to the hostile forces," said Kim, who oversaw the launch of the missile with a range that allows it in theory to hit anywhere in the United States.

Depending on their design, the missiles can be equipped with a nuclear warhead. On Monday, the missile flew some 1,000 kilometers from a steep launch angle before falling into the sea.
