In pictures: 80th anniversary of D-Day
Events to mark the 80th anniversary of D-Day are taking place in France and the UK on Thursday.
Commemorations began on Wednesday, which saw the King make his biggest speech since his cancer diagnosis - addressing a crowd in Portsmouth on the eve of the anniversary.

Britain's wartime prime minister, Sir Winston Churchill, called it "the most complicated and difficult" operation of World War Two, leading to the eventual liberation of France from Nazi occupation.
The UK's national commemorative event in Portsmouth was led by Dame Helen Mirren.
She said: "The presence today of some of those who contributed to that remarkable venture is an extraordinary privilege. Your bravery remains as inspiring now as it was eight decades ago."
D-Day veteran Roy Hayward was met with a standing ovation when he walked on stage on Southsea Common.
He was severely injured in Normandy, both his legs had to be amputated below the knees. He said he represented all the “men and women who put their lives on hold to go and fight for democracy and this country”.
The Red Arrows and a pair of Dakota military transport aircraft seen with their invasion stripes took part in a fly-past.
King Charles who attended with his wife Queen Camilla, paid tribute to the veterans who embarked in Portsmouth 80 years ago.
“It is our duty to ensure that we and future generations do not forget their service and their sacrifice in replacing tyranny with freedom.”
Prince William sat alongside Prime Minister Rishi Sunak and his wife Akshata Murty.
During his address, the Prince of Wales said: “We will always remember those who served and those who waved them off. The mothers and fathers, brothers and sisters, sons and daughters who watched their loved ones go into battle, unsure if they would ever return."
Labour leader Sir Keir Starmer posed for a photo ahead of the start.
The event included a number of performances, including one by actress Emma Barton, who sang Sing As We Go, a song originally performed by Gracie Fields.
In Cumbria, lone bagpiper Richard Cowie played on the deck of a traditional steamer at Bowness-on-Windermere to honour the D-Day piper Bill Millin, who played on the Normandy beaches on D-Day to confound the enemy and boost the morale of allied troops.
Across the channel in France, ceremonies are also taking place ahead of the main event on Thursday.
