The White House has defended US President Donald Trump's decision to miss a memorial event on Saturday after he faced a backlash.
Mr Trump, who was in France to mark the centenary of World War One's end, cancelled a visit to a US military cemetery because it was raining.
Bad weather and "near-zero visibility" grounded the presidential helicopter, White House officials said.
French, German and Canadian leaders attended memorial events on Saturday.
However, Mr Trump was reluctant to bring extra disruption to Paris traffic for a last-minute motorcade, his officials said.
"President Trump did not want to cause that kind of unexpected disruption to the city and its people," press secretary Sarah Sanders said, noting the trip was 60 miles (96km) north-east of Paris.
Mr Trump spent much of Saturday at the American ambassador's residence, and visited another US cemetery in a Paris suburb on Sunday.
Critics observed how Canadian Prime Minister Justin Trudeau had travelled 118 miles outside Paris to attend a ceremony - in the rain - at a cemetery in Vimy.
Notable criticism came from British Defence Minister Tobias Ellwood, who took an apparent swipe at the president on Twitter, saying "rain did not prevent our brave heroes from doing their job".
His comments followed a scathing rebuke from Sir Nicholas Soames, a grandson of the wartime British leader Sir Winston Churchill.
The MP tweeted that Mr Trump was not fit to represent the US and said that he was a "pathetic inadequate" for not defying the weather "to pay his respects to the fallen".

Rain was a regular feature on the Western Front. Thankfully it did not prevent our brave heroes from doing their job. https://t.co/2wd6Yq9VK3
The US president also received backlash from Americans, such as former Secretary of State John Kerry, who said "raindrops" should not have stopped his visit.
Ben Rhodes, who served as a deputy national security adviser under former US President Barack Obama, also hit back saying weather was not an excuse.
President @realDonaldTrump a no-show because of raindrops? Those veterans the president didn’t bother to honor fought in the rain, in the mud, in the snow - & many died in trenches for the cause of freedom. Rain didn’t stop them & it shouldn’t have stopped an American president.— John Kerry (@JohnKerry) November 11, 2018

I helped plan all of President Obama’s trips for 8 years. There is always a rain option. Always. https://t.co/exZNlONQOp— Ben Rhodes (@brhodes) November 10, 2018
A delegation of senior US officials went in the president's place to the Aisne-Marne American Cemetery and Memorial, the White House said.
The US president also opted to miss the Paris Peace Forum, which is run by his French counterpart Emmanuel Macron and began on Sunday afternoon.
Last year, foggy weather caused similar security concerns which prevented Mr Trump from visiting the demilitarised zone between North and South Korea.
