Seventy years to the day since thousands of Allied soldiers stormed the beaches of northern France, ceremonies are being held to remember D-Day.
World leaders gathered at Ouistreham - near the beach codenamed Sword - to remember the largest amphibious assault in history.
About 650 UK veterans attended alongside the Queen, US President Barack Obama, Russia's Vladimir Putin and Francois Hollande of France.
During her speech at the Elysee Palace, the Queen said of the UK and France: "We are two of the trustees of international peace and security."
Paris's presidential palace played host to a banquet for 19 visiting heads of state
In Arromanches-les-Bains, in Normandy, the Duke and Duchess of Cambridge joined veterans and members of the Normandy Veterans Association for a service to mark the 70th anniversary of D-Day
In a speech, Prince William said it was vital the sacrifices of D-Day and the campaigns in Europe are "never forgotten by our generation and generations to come". He then laid a wreath as part of a service in Arromanches
The Duke said he had the "privilege of meeting some of the veterans who were present on that great and terrible day". Earlier the Duchess of Cambridge talked to veterans at a tea party.
The commemoration was held near Gold Beach, where British troops scrambled ashore on D-Day, and included a fly-past by a Dutch B-25 Mitchell and a Spitfire
Earlier, heads of state including the Queen, US President Barack Obama and Russia's Vladimir Putin were present for the major event of the commemorations held on the beach in Ouistreham

Canadian troops were responsible for storming one of the five D-Day beaches - codenamed Juno - and on Friday Jessica Graves scattered the ashes of her grandfather William "Boots" Bettridge, who was part of the attack in 1944
On Gold Beach in Normandy, where British soldiers landed 70 years ago, hundreds of Union Flags have been planted in the sand
Earlier, Francois Hollande and Barack Obama spoke at a service in Colleville-sur-Mer. Mr Hollande said Nazi leaders were over-confident because they "could not foresee that in democracies a great ideal gives birth to great bravery". Mr Obama said the US commitment to liberty was "written in blood" on Normandy's beaches
President Obama also met veterans and during his speech he asked them to stand or raise an arm to be recognised by the crowd
At a war memorial in Bayeux the Queen laid a wreath. Politicians, military personnel and veterans followed, laying tributes of their own

Fireworks lit up the skies over Pegasus Bridge in northern France on Thursday night to mark the time when British glider-borne troops arrived to capture it ahead of the landings. The bridge was secured within 10 minutes - the first engagement of D-Day
