U.S. President Barack Obama will join millions of Americans in observing the annual Veterans Day holiday Monday.
Mr. Obama will host a breakfast at the White House for a group of military veterans and their families, and will later participate in a traditional wreath laying ceremony at Arlington National Cemetery.
The holiday was first observed in the United States 1919 as Armistice Day, marking the day one year earlier, November 11, 1918, when the United States and its allies reached a formal agreement with Germany to end World War One.
In the aftermath of both World War Two and the Korean War, the holiday was renamed Veterans Day in 1954 to honor American veterans of all wars.
The other military-themed holiday in the U.S., Memorial Day, is observed in May to honor those who died in military service.
In Britain Sunday, thousands gathered in central London to observe a two-minute moment of silence during Remembrance Sunday, which is observed on the nearest Sunday to the anniversary of the end of the so-called "war to end all wars."
