PARIS (AP) For the 100th anniversary of World War I, officials from about 30 countries are meeting in Paris to plan four years of commemorative events.
At least 8.5 million soldiers are believed to have perished in the 1914-18 war.
France, where the majority of Western Front fighting took place, is taking a leading role in the preparations.
Senior officials from countries including the U.S., Britain and Australia were gathering Thursday under the Arc de Triomphe for a ceremonial re-lighting of the eternal flame that marks the tomb of France's unknown soldier.
Meetings continue Friday under the golden dome of the 17th-century Invalides monument, hosted by France's veterans' affairs minister, Kader Arif.
