Volunteers on Friday helped to bury more victims of the devastating earthquake and tsunami that hit the Indonesian city of Palu. A mass grave was dug on top of a mountain range outside the city. One week after a magnitude 7.5 quake spawned a deadly tsunami on the island of Sulawesi, countless people have yet to find their loved ones - both survivors and the dead. As of Thursday, the government put the death toll at 1,424, with 113 people missing. Many families, though, never registered their losses with police, while others failed to identify them before they were buried anonymously in mass graves.
