North Korea’s attempt to put its first military satellite into orbit failed Wednesday. The unsuccessful launch was a setback for leader Kim Jong Un. Kim has pushed to increase his country’s military strength with new weapons. State news agency KCNA said the new Chollima-1 satellite launch rocket failed because of instability in the engine and fuel system. The launch was North Korea’s sixth satellite launch attempt, but its first since 2016. The launch caused emergency alerts and brief evacuation warnings in parts of South Korea and Japan. The warnings were later cancelled with no damage reported.
