SEOUL (AFP) - North Korea last year tested a rocket to carry long-range missiles in an apparent attempt to showcase its weapons capability to the United States, a report said Sunday. The commu nist state conducted the rocket engine test at the new Tongchang-ri missile base on the west coast in October, Yonhap news agency said, citing a senior Seoul official. "We believed that the test, carried out at an hour when the US military satellite could detect it, was aimed at showcasing its missile threats," Yonhap quoted the official as saying. Satellite images taken in January showed that North Korea had completed a launch tower at the Tongchang-ri missile base.
