Americans honored fallen service members on Memorial Day with President Barack Obama leading the nation's commemoration by laying a wreath at the Tomb of the Unknowns at Arlington National Cemetery. Dozens of ceremonies were held across the nation to honor Americans killed in wars.

The holiday long-weekend also marks the beginning of the summer travel season in the U.S.
