PLACER COUNTY, Calif. --
A school was severely damaged after flames erupted in Placer County.

Fire officials said at least three classrooms were destroyed and estimate damages at more than $100,000.
One firefighter also hurt his back.
Officials said the fire was especially difficult to for crews to tackle because the same department was called to a house fire 10 minutes prior.
Other agencies stepped in to help.
Fire officials said they are now looking into what started the fire blaze.
