Only one military dog tag allegedly was provided to U.S. officials last week when North Korea handed over 55 boxes of what it said were the remains of American soldiers killed in the Korean War, The Associated Press reported Tuesday.

A U.S. defense official, who spoke on the condition of anonymity, told the AP that it could take months or years to identify the remains. The official could not say what name was on the dog tag or whether it even belonged to an American.

The remains were handed over last week in the coastal city of Wonsan, North Korea, before they were flown back to an air base in South Korea.

While the fighting in the Korean War lasted from 1950 until 1953, the war never formally ended and a peace treaty was never signed. There were estimated 5,300 Americans who did not return home from the conflict.

A repatriation ceremony for the remains is set for Wednesday. After that, they will be taken to Hawaii, where they will begin undergoing forensic analysis to try to identify whom they belong to.

A 1994 RAND Corporation report notes that, even when dog tags have been provided in the past, the remains have not always been able to be identified as those of U.S. troops, Reuters reported.

Pyongyang has said it has the remains of about 200 people believed to be U.S. troops who died in the Korean War.
