North Korean authorities provided just one dog tag when handing over 55 boxes of remains believed to belong to U.S. service members killed in the Korean War, the Associated Press reports. A U.S. defense official quoted by the news agency said no other information was provided to assist in identifying the remains. U.S. specialists have yet to confirm whether the remains even belong to dead American troops, despite plans for a repatriation ceremony at Osan Air Base in South Korea on Wednesday. Vice President Mike Pence is also due to take part in a separate ceremony to hail the return of the remains, which President Trump has touted as a major breakthrough in relations with North Korea. The families of the more than 7,700 American veterans who went missing during the 1950-53 Korean War are unlikely to find much comfort in the situation, however, as they will have to wait months or even years for forensic analysis to identify the bodies.
