LOS ANGELES (AP) — More than 250 firefighters raced to the hills overlooking Los Angeles to battle a blaze that ignited Tuesday afternoon in thick brush surrounded by mansions.

Helicopters repeatedly dropped water on the flames as teams of firefighters on the ground set up a perimeter around the houses.

Firefighters aided by light winds and moderate temperatures quickly made progress against the 32-acre blaze and no homes were immediately lost, said Los Angeles Fire Department spokeswoman Margaret Stewart.

People in homes on one street closest to the flames were asked to evacuate.
