It is believed to be the first launch by the secretive country since June 8, when it tested eight short-range ballistic missiles. The latest launch comes as South Korean President Yun Suk-yeol called for diplomacy aimed at building lasting peace between the rivals amid tensions over the North’s accelerating weapons program. Speaking at a news conference on Wednesday, Mr. Yun said he does not want political change in North Korea that brings violence and urged North Korea to return to dialogue aimed at exchanging denuclearization steps for economic benefits. The calls for talks come despite threats of “deadly retaliation” by Kim Jong Un’s sister as she blamed propaganda leaflets from South Korea found near the border for causing the coronavirus outbreak. The missiles were fired from the west coast city of Oncheon early Wednesday, a South Korean military source said. Details about their range or altitude were not immediately available. The launch comes as South Korea and the US began a four-day preliminary joint exercise on Tuesday.
