A cannon fired by a Civil War re-enactment group at a parade in Utah sparked an explosion that sent three children to the hospital.
Investigators say sparks from the cannon landed on a large pouch containing additional charges for the weapon and the pouch then exploded. The accident occurred at the start of the Summerfest Parade in Orem, about 45 miles south of Salt Lake City.
Police say all three children were treated at the scene and taken by ambulance to a local hospital in stable condition. Orem police Sgt. John McCombs said Sunday that updates on their conditions weren't available.
The children were participating in the parade as part of the re-enactment group.
The explosion is under investigation.
