REGINA - RCMP say a seven-year-old boy from Turner Valley, Alta., and his 11-year-old sister are among the four dead after a collision between a Canadian Pacific train and a camper van in Saskatchewan.
The crash Thursday evening was at an uncontrolled crossing near Broadview, about 150 kilometres east of Regina.
Another sibling, a 15-year-old boy who was driving, was also hurt.
It is legal in Saskatchewan for 15-year-olds to drive if they have a learner's permit and an adult is in the vehicle with them.
The children's 42-year-old mother was also injured in the crash.
An 11-year-old girl from Chestermere, Alta., and an 18-year-old woman from the Whitewood district in Saskatchewan were also killed.
RCMP say they are not related to the others in the van nor to each other.
No names have been released.
