North Korea on Thursday launched two short-range missiles, marking the second weapons test in less than a week and further straining U.S.-led efforts toward denuclearizing the Korean Peninsula. The South Korean joint chiefs of staff announced the launch in a statement, saying the missiles were fired from the northwest city of Kusong and traveled roughly 260 miles to the east. American negotiators are currently in South Korea for discussions on how to break the impasse following two high-level summits between President Donald Trump and North Korean leader Kim Jong Un that failed to secure any lasting changes. The launch comes less than a week after North Korea fired several short-range missiles on Saturday, the first such weapons test since November 2017. Trump has previously cited North Korea's lull in missile and nuclear tests as evidence that his outreach to the Hermit Kingdom was proving successful.
