Japan has warned North Korean missiles pose “a serious threat” after the country carried out new tests in defiance of international sanctions. North Korea launched two new medium-range missile on Wednesday, within hours of each other, with one flying about 400km (250 miles) and reaching an altitude of 1,000km.
Both achieving a significant increase in flight distance over previous failed launches, South Korea’s defence ministry said.
The launch came about two hours after a similar test failed, South Korea’s military said, and covered 400 km (250 miles), more than halfway towards the southwest coast of Japan’s main island of Honshu.
The launches and earlier nuclear tests show continued defiance of international warnings and a series of U.N. Security Council resolutions and sanctions, which North Korea rejects as an infringement of its sovereignty.
