A brush fire raging along a southern California riverbed prompted the evacuation of two nearby amusement parks, but no homes were threatened and no serious injuries were reported.
Firefighters managed to halt the advance of the blaze within several hours, carving containment lines around 20 per cent of its perimeter, the dispatcher said.
The blaze erupted at about noon (1600GMT) in the Valencia community of Santa Clarita, about 35 miles northwest of Los Angeles.
