Ten people have been taken to hospital after a head-on crash between a school bus and a van in County Donegal, a few miles from the Irish border.
The casualties included eight secondary school pupils and the drivers of both vehicles.
The collision happened on the road between Londonderry and St Johnston, shortly before 08:00 BST on Thursday.
No-one has sustained life-threatening injuries, according to Garda Inspector Michael Harrison.
He told BBC News NI that 20 secondary school pupils were on board the 53-seater bus at the time.
They were travelling to different schools in Raphoe - Deele College and the Royal and Prior Comprehensive School.
Their bus crashed on the R265, in the townland of Carrickmore, between St Johnston village and Lifford town.
The officer said the road would have been busy at the time, as many drivers from Northern Ireland use the road to travel between Derry and Strabane.
He appealed for witnesses to come forward.
Garda crash investigators have left the scene and the vehicles have been removed.
The road is expected to re-open shortly.
