COLLEVILLE-SUR-MER, France (AP) — When the sun rises over Omaha Beach, revealing vast stretches of wet sand extending toward distant cliffs, one starts to grasp the immensity of the task faced by Allied soldiers on June 6, 1944, landing on the Nazi-occupied Normandy shore. Several ceremonies are scheduled Sunday to commemorate the 77th anniversary of the decisive assault that led to the liberation of France and western Europe from Nazi control, and honor those who fell. On D-Day, more than 150,000 Allied troops landed on the beaches code-named Omaha, Utah, Juno, Sword and Gold, carried by 7,000 boats. This year on June 6, the beaches stood vast and empty as the sun rose, exactly 77 years since the dawn invasion. For the second year in a row, anniversary commemorations are marked by virus travel restrictions that have prevented veterans or families of fallen soldiers from the U.S., Britain, Canada and other Allied countries making the trip to France. Only a few officials were allowed exceptions. Most public events have been canceled, and the official ceremonies are limited to a small number of selected guests and dignitaries.
