Events are taking place around the world to commemorate the 80th anniversary of the D-Day landings in Normandy, France.
On June 6, 1944, tens of thousands of Allied troops landed on five stretches of the Normandy coastline, codenamed Utah, Omaha, Gold, Juno and Sword.
It was the largest amphibious invasion in history and launched a campaign that laid the foundations for the Allied defeat of Nazi Germany in World War II.
"We're not far off from the time when the last living voices of those who fought and bled on D-Day will no longer be with us, so we have a special obligation," US President Joe Biden said in a speech at the Normandy American Cemetery and Memorial. "We cannot let what happened here be lost in the silence of the years to come."
