COUNCIL BLUFFS, Iowa (AP) – Authorities say some Boy Scouts experimenting with gunpowder for a ceremony have been injured in an explosion and fire at a Council Bluffs Home. Fire investigator Dan Roberts told Omaha television station KETV that the accident occurred around 8:10 p.m. Thursday.  A Council Bluffs Fire Department report says the group was experimenting with gunpowder while working on an Order of the Arrow ceremony.

The department says four minors and two adults suffered mostly second-degree burns and were taken to area hospitals. Two of the injured were taken to a burn center in Lincoln, Neb. One adult remains hospitalized in Omaha, Neb., and the three remaining injured people have been released.

The fire marshal’s office is investigating.
