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 US and North Korea over Pyongyang’s weapons programs.

Stephen Biegun, the US special envoy for North Korea will travel to Japan and South Korea next week to coordinate efforts to secure the denuclearization of North Korea. News of Biegun’s trip came after US President Donald Trump said last Saturday that Kim had told him he was ready to resume stalled denuclearization talks with the Us and would stop recent missile testing as soon as US-South Korea military exercises that have been held this month end.
