HANOI, Vietnam — Officials say remains believed to be those of seven American servicemen killed during the Vietnam War have been sent back to the United States from central Vietnam.

Ron Ward of the U.S. MIA office in Vietnam says the remains were loaded onto a U.S. military aircraft at Danang airport today and flown to a laboratory at Hickam Air Force Base for identification.

The remains were recovered over the last two months from sites in Vietnam.

Nearly 1,800 U.S. servicemen are still unaccounted for throughout Southeast Asia from the Vietnam War, which ended in 1975. Of those, 1,353 are believed to be in Vietnam.

An estimated 58,000 Americans and 3 million Vietnamese were killed in the war.
