Guam

North Korea has launched another missile over Japan, a day after it threatened to “sink” the country and turn the US “into ashes and darkness”.

North Korea on Saturday morning fired what are believed to be three short-range ballistic missiles, one of which exploded shortly after launch, the U.S. Pacific Command said.

The missiles were launched near Kittaeryong between 6:49 a.m. Seoul time (5:49 pm. Friday ET) and 12:19 p.m. The second missile “appears to have blown up almost immediately,” Pacific Command said.

North Korea has increased its efforts to produce parts for a new nuclear reactor it is building while continuing to operate the main existing one that provides fuel for its atom bombs, the U.N. nuclear watchdog has said in an annual report on Friday, Reuters Reported.

American President Donald Trump has spoken of raining "fire and fury" on North Korea after Pyongyang, having tested missiles that could potentially hit US interests, announced that it was looking at a strike at the US Pacific territory of Guam. Sabre rattling is a part of the fraught ties between the two countries.

North Korea's leader has delayed a decision on firing missiles towards Guam while he watches U.S. actions a little longer, the North's state media said on Aug. 15, as South Korea's president said Seoul would seek to prevent war by all means.

U.S. President Donald Trump has hardened his warning that North Korea would face "fire and fury" if it kept threatening the U.S., saying maybe that tough talk "wasn't tough enough."

China should remain neutral if North Korea launches an attack that threatens the United States, a Chinese state-run newspaper said on Friday, sounding a warning for Pyongyang over its plans to fire missiles near the US Pacific territory of Guam, The Independent reported.
