North Korean leader Kim Jong Un oversaw the test-firing of a new weapon again on Friday morning, state media KCNA said on Saturday.
North Korea launched at least two short-range ballistic missiles on Friday, South Korea's military said, its sixth round of weapons launches since late July, complicating efforts to restart talks between the United States and North Korea over Pyongyang's weapons programs.
Stephen Biegun, the U.S. special envoy for North Korea will travel to Japan and South Korea next week to coordinate efforts to secure the denuclearization of North Korea, the State Department said on Friday.
News of Biegun's trip came after U.S. President Donald Trump said last Saturday that Kim had told him he was ready to resume stalled denuclearization talks with the United States and would stop recent missile testing as soon as U.S.-South Korea military exercises that have been held this month end.
The North has protested against joint U.S.-South Korea military drills, which kicked off last week, calling them a rehearsal for war.
