Three small storage buildings and a car were destroyed and a garage damaged in a brush fire that burned four acres near Delta Flats in the Angeles National Forest, authorities said. No injuries were reported in the fire, which broke out near Big Tujunga Canyon Road and Delta Flats, the U.S. Forest Service said. The fire burned out of control for about two hours, slightly damaging a garage at a home near the boundaries of the national forest and destroying a car and three storage buildings within the forest. About 60 firefighters worked to surround the blaze. Its cause was under investigation.
