RAVENSCRAG, Sask. - Two boys have been killed in an accident involving a tractor towing a baler in southwestern Saskatchewan.

RCMP say a 16-year-old and a 10-year-old were going downhill on a gravel road Wednesday near Ravenscrag when the four-wheel-drive tractor hit a steep and rough ditch.

It then tumbled into a ravine.

Both boys were thrown from the tractor and were found dead at the scene.

Police have released no further details.
