France's President Francois Hollande, right, hugs German President Joachim Gauck, left, as they pay respect in the crypt of the the National Monument of Hartmannswillerkop, in Wattwiller, eastern France, Sunday, Aug. 3, 2014, to mark the 100th anniversary of the outbreak of World War I. On this day 100-years ago, in 1914, Germany declared war on France, at the beginning of the first global war, which centred on Europe and resulted in over nine million combatants being killed.
