WASHINGTON (CNN) - Flags are being flown at half staff at the White House and throughout the country Tuesday in memory of Army Corporal Frank Woodruff Buckles, the last surviving American veteran of World War I.
Buckles, who died last month at age 110, will be interred with full military honors at Arlington National Cemetery today (watch on cnn.com/live).
President Obama issued a proclamation ordering on the day of his interment that flags be flown at half staff at the White House and "upon all public buildings and grounds, at all military posts and naval stations, and on all naval vessels of the Federal Government in the District of Columbia and throughout the United States and its Territories and possessions" until sunset.
The order also applies to all United States embassies and other facilities abroad, including all military facilities and naval vessels and stations.
