North Korea continued a series of controversial weapons tests on Monday with the launch of at least one short-range ballistic missile. The apparent Scud-class ballistic missile flew about 280 miles before coming down in the sea in Japan's economic zone, South Korean officials said. The launch came after two successful tests of North Korean mid- and long-range missiles in the last two weeks. President Trump responded on Twitter that "North Korea has shown great disrespect for their neighbor, China, by shooting off yet another ballistic missile ... but China is trying hard!"
North Korea's refusal to curb its missile and nuclear weapons programs in defiance of United Nations resolutions and international sanctions has ratcheted up tensions with the U.S. and other nations. The U.S. on Tuesday plans to conduct its first test of a missile defense system intended to intercept ICBMs.
