In a rare public acknowledgment, North Korean dictator Kim Jong Un vowed to punish those responsible for the failed launch of the nation’s second navy destroyer and called the incident a criminal act. North Korean media reported that the “serious accident” involving a new 5,000-ton destroyer happened on Wednesday, May 21, along the country’s northeastern coast.The incident reportedly unfolded while Kim and a large crowd watched the event. The vessel crashed after it lost balance and slid down a “slipway” where it was being launched.
