HELENA, Mont. (AP) - A fire engine and another vehicle collided on U.S. Highway 12 in southwestern Montana, causing an explosion and fire that killed at least five people.

Jefferson County Sheriff's Deputy Bob Gleich says the collision happened about 9 p.m. Thursday about 10 miles east of Helena, forcing both vehicles into the ditch. Witnesses said the vehicles immediately caught fire, and Gleich says they melted together in the resulting inferno.

Montana Highway Patrol Trooper Jay Nelson told KTVH-TV that at least five people were killed.

The Gallatin County sheriff's office said Friday that one of the victims was Three Forks Fire Chief Todd Rummel. The names and ages of the others involved haven't been released.
