The siren at Camp Casey, which is near the border with North Korea, went off by “human error” at about 10pm on Thursday, said US Army Lieutenant Colonel Martyn Crighton, a public affairs officer for the US Second Infantry Division. The operator immediately identified the mistake and alerted all units at the base of the false alarm, which did not interfere with any operations, Crighton said in an e-mail yesterday. The incident came after Japan Broadcasting Corp caused panic early on Friday by mistakenly sending a news alert saying that North Korea had fired a missile over Japan that landed in the sea off Hokkaido. There are concerns that Pyongyang could do something provocative if Washington does not back down and relieve sanctions imposed on North Korea’s broken economy. North Korea fired two missiles over Japan during a provocative run in weapons tests in 2017, which also included three flight tests of developmental intercontinental ballistic missiles (ICBMs), which demonstrated potential capabilities to reach the US mainland.
