NEW ORLEANS — Twenty years after Hurricane Katrina devastated the U.S. Gulf Coast with catastrophic storm surge and flooding, New Orleans marked the storm's anniversary Friday with solemn memorials, uplifting music and a parade that honored the dead, the displaced and the determined survivors who endured and rebuilt.

Dignitaries and longtime residents gathered under gray skies at the memorial to Katrina's victims in a New Orleans cemetery where dozens who perished in the storm but were never identified or claimed are interred.
