SEOUL/WASHINGTON (Reuters) - North Korea's leader witnessed the test of a newly developed high-tech weapon, the country's state media reported on Friday, while Pyongyang also released a U.S. prisoner, sending conflicting signals at a time of sensitive negotiations.
Kim Jong Un's visit to the test site of what North Korea's state media called a "tactical weapon" that could protect North Korea like a "steel wall" threatened to sour the diplomatic atmosphere at a time when negotiations between North Korea and the United States appear to have stalled.
