REDDING, Calif. (AP) — A Northern California wildfire that authorities say was sparked by exhaust from a truck at an illegal marijuana plot has prompted new evacuations.

The Bully Fire, which started Friday, has destroyed eight homes and 10 other structures.

Meanwhile, a wildfire in southern Oregon has destroyed six homes and 14 other buildings.

Lightning strikes have set off dozens of other blazes in the state and in Idaho.
