A major incident has been declared after a school bus and a car were involved in a crash in Drumquin, Co Tyrone.
More than 50 people - mostly children - have been injured after the collision on Omagh Road, but it is understood none of them are seriously injured.
The bus and the car ended up on their sides in a field.
Northern Ireland Ambulance Service spokesman John McPoland said: "52 people were treated at the scene but none of their injuries were serious. The vast majority were checked as a precaution because of their age."
"Six people have slightly more than minor injuries. This would include children who banged their heads off the bus windows but no one went through any windows."
These children, and the occupants of the car, have been taken to the South West Acute Hospital and Altnagelvin Hospital.
Omagh Road has been closed between Segully Road and Drumrawan Road.
The crash happened in the Stormont constituency of Northern Ireland's Deputy First Minister Martin McGuinness.
He has tweeted: "Relieved to hear there are no serious injuries to pupils & adults in this morning's bus & car accident on Drumquin-Omagh Rd #bestwishestoall."
