French President Francois Hollande has commemorated the 100th anniversary of World War I with an appeal to players in the Gaza conflict to put animosities aside — just as France and Germany have done.

Hollande gave an impassioned speech Sunday in Vieil Armand in Alsace, marking Germany's declaration of war on France on Aug. 3, 1914. He was joined by German President Joachim Gauck — the first time Germany's head of state has attended the event.

Hollande remembered the 30,000 men killed around Vieil Armand, known in German as Hartmannswillerkopf, but pointed out that France and Germany "who were regarded as hereditary enemies," reconciled.

He appealed to the world to use Franco-German peace as a lesson in peacemaking and "to stop the suffering of the civilian population," in Gaza.
