North Korea said on Oct. 20 that it had test-fired a newly developed ballistic missile from a submarine, in its first such underwater test-launch in two years and one it says will bolster its military's undersea capabilities.

U.S. President Donald Trump on May 26 downplayed recent North Korean missile launches as he teed off a state visit to Japan with a round of golf with Prime Minister Shinzo Abe and a trip to the sumo.
