LOS ANGELES, Sept. 7 (Xinhua) -- The brush fire that ignited Wednesday afternoon and scorched roughly 8 square kilometers in Riverside County of Southern California, was 35 percent contained on Saturday morning, authorities said.

Crews managed to increase the containment from 25 percent overnight, when "fire activity was minimal," according to an update from California Department of Forestry and Fire Protection (CalFire).

CalFire expected the blaze, dubbed the Tenaja Fire, to be fully contained by next Tuesday.

Some 700 fire personnel continued to work on controlling the flames since they broke out around 4 p.m. in La Cresta on Wednesday and quickly spread.

About 2,000 homes were threatened after the fire broke out, triggering mandatory evacuations for hundreds of residents. Evacuation orders and warnings were lifted Friday morning.

The fire damaged two homes and left three firefighters with injuries that were not life threatening, according to CalFire.
