SEOUL, South Korea (AP) — North Korea has fired multiple short-range ballistic missiles toward its eastern waters, days after the end of the South Korean-U.S. military drills that the North views as an invasion rehearsal. The launches were North Korea’s first known missile testing activities in about a month. Japan, South Korea and the U.S. condemned the launches as threats to regional peace. Observers say the missiles’ fight distances indicate they are weapons targeting major facilities in South Korea, such as its military headquarters in the central region. The U.S. and South Korea recently concluded 11 days of joint drills that involved computer simulations and a variety of field exercises.
