Our live coverage has ended for the evening, but stay with CNN to read more about Armistice centenary commemorations. Here's everything you need to know:
- French President Emmanuel Macron, rebuked nationalism at a ceremony at the Arc de Triomphe in Paris, saying, "Nationalism is a betrayal of patriotism."
- US President Donald Trump was widely criticized for canceling a visit to an American cemetery 50 miles outside of Paris on Saturday due to rain, which sometimes grounds the Marine One helicopter. The President visited a different American cemetery, this one much closer to Paris, on Sunday.
- A topless protester with the words "fake" and "peace" written on her body ran at Trump's motorcade as it was approaching the Arc de Triomphe, before being apprehended by authorities.
- In London, Queen Elizabeth II and German President Frank-Walter Steinmeier laid wreaths at the Cenotaph war memorial. More than 10,000 people also walked through the city past the Cenotaph.
US President Donald Trump paid his respects to the thousands of American soldiers who died in World War I, saying, "It is our duty to preserve the civilization they defended and secure the peace they so nobly gave their lives for one century ago."
Speaking at Suresnes American Cemetery, just outside Paris, Trump called out to six US veterans from World War II who were in the crowd, and a 13-year-old American boy who had saved his money to attend the event.
"On this day in the year 1918, church bells rang out and celebrations ensued," Trump told the crowd.
"But victory had come at a terrible cost," he added. "Countless would come home bearing the grisly scars of trench warfare."
Paying tribute to the French and American soldiers who fought side-by-side, Trump said: "You cannot fight better than we fought together."
US President Donald Trump is at Suresnes American Cemetery, just outside Paris, where 1,541 Americans who died in World War I and 24 from World War II, are buried.
Trump will "make a speech in honor of our great heroes!" he wrote in a tweet.
The president is due back in Washington by Sunday evening.
Thousands of people across the UK have taken part in Armistice anniversary services -- including in Scotland.
A giant blimp of a baby Donald Trump was launched in central Paris, in protest against the US President's visit to the city.
The blimp, which depicts a baby Trump clutching a mobile phone and sporting a diaper, was first floated in London in July also in protest against the President's UK visit.
An Anti-Trump protest is due to take place in Place de la Republique later Sunday.
“It’s important for me to be here today to send a message to Macron for having invited Trump," said Sophie Haas, who helped to organize the blimp demonstration.
"By inviting Trump, Macron is supporting Trump’s racist, xenophobic, sexist policies all over the world," she said.
"We’re hoping for a few thousand people [at the protest] and praying the rain won’t dampen spirits!”
Giant portraits of fallen World War I soldiers have been etched into the sand of 32 beaches across the UK, as part of Armistice anniversary commemorations.
