President Emmanuel Macron led tributes to the millions of soldiers who died during WWI on Sunday, holding a solemn ceremony attended by dozens of world leaders in Paris to commemorate the centenary of the Armistice.
US President Donald Trump, Russian President Vladimir Putin, German Chancellor Angela Merkel and dozens of princes, monarchs, presidents and prime ministers joined Macron to mark the moment guns fell silent across Europe a century ago.
Those who fought in the trenches of World War One lived through an unimaginable hell, Macron said in a 20-minute address, highlighting that as well as the deaths of 10 million troops, millions of women were widowed and children orphaned.
"The lesson of the Great War cannot be that of resentment between peoples, nor should the past be forgotten," said Macron, sorrow etched on the faces of former French soldiers standing to attention around him during the ceremony.
"It is our deeply rooted obligation to think of the future, and to consider what is essential."
The commemoration is the centrepiece of global tributes to honour those who perished during the 1914-18 war and to commemorate the signing of the Armistice that brought the fighting to an end at 11 am on November 11, 1918.
In a glass canopy at the foot of the Arc de Triomphe, built by Emperor Napoleon in 1806, Trump, Merkel, Macron, Putin and the other leaders listened through earpieces as the French president spoke. Putin, who was last to arrive at the ceremony, gave Trump a brief thumb's up as he greeted them.
As Trump's convoy was making its way up the Champs Elysees to the Arc de Triomphe, a bare-breasted protester from the Femen radical feminist group ran towards his motorcade, coming within a few metres, before being apprehended by police.
