A brush fire that scorched six acres and prompted evacuations in Santa Clarita was 65% contained Wednesday morning.

The fire was reported at about 11 p.m. Tuesday near Center Pointe Parkway and Isabella Parkway, and was burning uphill, according to the city of Santa Clarita. Just after midnight, city officials said progress of the fire had been stopped.

The Los Angeles County Fire Department reported 200 firefighters and water-dropping aircraft contained the swift-moving flames to six acres and kept the fire from spreading to about 50 homes near Isabella Parkway and Golden Triangle Road.

Evacuees in homes along Isabella Parkway, Aurora Lane and Sheldon Avenue in Canyon Country were allowed to return home at about 1:30 a.m., the Los Angeles County Sheriff's Department said.

Officials said the fire was 65% contained and crews would work to reinforce firelines and mop up hot spots throughout the early morning hours.

No injuries were immediately reported. The cause of the fire was unknown.
