(AP) — Two Boy Scouts who were hospitalized with burns after a gunpowder explosion in Council Bluffs last week have been released.

The two boys, Jared Holcomb and Scott Brown, had been treated at St. Elizabeth Regional Medical Center in Lincoln since the incident on Thursday.

The boys were hurt while experimenting with gunpowder at a Council Bluffs home in preparation for a spring ceremony.

Two other boys and two adults were also injured but didn’t have to be hospitalized as long. Holcomb and Brown were released from the Lincoln hospital on Saturday.
