JACKSON, Wyo. (AP) — An explosion at a propane dealer in the Wyoming tourist town of Jackson has forced the evacuation of several nearby businesses and a small school.

Police and emergency officials said Thursday that there were no immediate reports of injuries.

Authorities say multiple explosions occurred shortly before 1 p.m. at the AmeriGas store on the southwest edge of the town in northwest Wyoming. The AmeriGas store is about 2 miles from downtown Jackson.

A small independent high school, a grocery store and other small businesses nearby have been evacuated. A larger high school and middle school about a block away were not evacuated.

An employee of a nearby fitness center tells the Jackson Hole News & Guide that a large delivery truck had leaked propane just before the explosion.
