North Korea's Joint Chiefs of Staff say North Korea test-fired two short-range missiles on Thursday. Both missiles were fired 19 minutes apart. The missiles covered a distance of 450 km and reached an altitude of 60 meters. The first missile was fired at 7:06 a.m. Korean time and the second at 7:25 p.m. It was not immediately clear if the missiles were ballistic missiles. If confirmed to be a ballistic missile, it would be the first time since Biden became president that North Korea has violated a UN Security Council resolution. The last time North Korea tested a ballistic missile was about a year ago. Analysts say the latest developments by North Korea indicate that North Korea is now preparing to gradually escalate tensions with the United States and that its provocative actions have led to a disorganized US response. Can exceed Earlier on Sunday, North Korea tested two cruise missiles, but US President Joe Biden called it "normal" and said there was no change in North Korea's attitude.
