The death toll of a fire at a warehouse dance party in Oakland, California, late Friday night has reached 24 people, officials said Sunday, up from an initial count of nine bodies. About 15 people believed to have been in the building remain missing, and fire crews are slowly searching the rest of the badly damaged structure. Many people who were killed or injured in the blaze had difficulty escaping the warehouse, described as a labyrinth of artists' workspaces and illegal dwellings.
