North Korea tested a new ICBM engine Saturday at the national missile station near its west coast. The official news agency quoted “Dear Comrade Kim Jong Un” who watched the test as commenting: “Now we can mount an ever more powerful nuclear warhead on a new intercontinental ballistic rocket and put the den of evil in the United States, and all over the world, within our strike range." In March, Pyongyang claimed to have miniaturized a nuclear warhead to be mounted on ballistic missiles. DEBKAfile has reported that Tehran has shown interest in the project.
