TORONTO -- Police say three siblings ranging in age from six to 11 have died in a car crash near Sudbury, Ont.

Provincial police say the accident happened shortly before 9 a.m. on Wednesday while two families were driving back to the municipality of Chelmsford, Ont., on the outskirts of Sudbury.

Const. Michelle Coulombe says a 2007 Honda Accord driven by the children's mother left the highway and hit a rock cut.

Brothers Destiny and Flourish Osagie, aged 11 and 10 respectively, were pronounced dead at the scene, while their six-year-old sister Britney Osagie was pronounced dead in hospital later that day.

A 10-year-old boy not related to the Osagie family remains in hospital with life-threatening injuries, while the two mothers travelling in the car with the children were either unhurt or slightly injured.

Coulombe says officers are investigating the crash but no charges have been laid so far.
