SYRACUSE (AP) -- Authorities say several Syracuse elementary school students have been treated after pepper spray was discharged on their school bus.

The Post-Standard of Syracuse reports that emergency crews treated eight students for eye irritation after the spray was discharged around 7:30 a.m. Wednesday morning while the bus was taking them to school. 

There were about 30 students on the bus at the time. All were evacuated from the vehicle.

Syracuse police are trying to determine who discharged the pepper spray.
