North Korea test-fires suspected missiles a day after US and South Korea conduct a fighter jet drill

North Korea has fired suspected short-range ballistic missiles off its east coast a day after South Korea and the U.S. flew powerful fighter jets in a drill that the North views as a major security threat. South Korea’s Joint Chiefs of Staff says the launches were made from the North’s east coast on Monday afternoon. North Korea in recent months has extended its weapons testing as part of its efforts to enlarge and modernize its military capabilities while diplomacy with the United States and South Korea remains stalled. Observers say North Korea likely believes an upgraded weapons arsenal would give it leverage to win greater concessions from the U.S. if negotiations resume.
