SANTA CLARITA, Calif. - One of two wildfires burning in the hills and mountains around Interstate 5 north of Los Angeles was fully contained Saturday and authorities were getting an upper hand on the second one.

The 712-acre fire was contained late Saturday after breaking out Friday and briefly threatening an elementary school and about 20 homes, the Los Angeles County Fire Department said.

Some 350 firefighters battled the blaze Saturday amid unpredictable winds and rough terrain.
