Mourners offer prayers as they gather at the Ulee Lheue mass grave, one of the two major mass burial sites where victims of the 2004 Indian Ocean tsunami were laid to rest, in Banda Aceh on December 26, 2024, the 20th anniversary of the tsunami. On December 26, 2004, a magnitude 9.1 earthquake struck the coast of Sumatra in Indonesia and triggered a huge tsunami across the Indian Ocean that killed more than 220,000 people in a dozen countries.
