Esterhazy RCMP responded to an unusual collision in the Round Lake area, just off of Highway 247.
Two horses were pulling a wagon carrying about 20 kids, when the horses were spooked and took off in a full gallop.
The wagon then crossed a ditch and hit some trees, and while the wagon didn’t flip over, the collision with the trees did cause some injuries.
STARS Air ambulance did respond to one serious injury.
The Saskatchewan Health Authority said 15 people were treated in hospital with non-life threatening injuries. Nine people have been discharged.
