U.S. soldier Francis Lupo, who died 88 years ago in a World War I battle, has been buried with military honors at Arlington National Cemetery outside Washington.
Several people, including family and French military officers, attended the ceremony for Lupo, who had been listed as "missing in action" following an attack on German forces near Soissons, France in 1918. It became known as the Second Battle of the Marne.
In 2003, French archaeologists discovered some of Lupo's bone fragments while working on a conservation project. The remains were later identified by the Pentagon's POW-MIA (Prisoners of War - Missing in Action) office.
The Pentagon says Lupo, who was killed at age 23, is the first World War I soldier to be identified by the POW-MIA office.
Lupo's name had been earlier inscribed on the walls of the memorial chapel at the Aisne-Marne American Military Cemetery, not far from where he was killed. Several other missing soldiers are also listed.
The Pentagon says that of the more than 12,000 U.S. soldiers who fought in the Second Battle of the Marne, all but about 4,000 were killed, wounded, taken prisoner, or listed as missing.
