Crash between semi and ambulance on Highway 1 near Pense

Moose Jaw and Regina firefighters are on the scene of a crash between a semi, ambulance and other vehicles on Highway 1 near Pense. 

Fire officials say at least seven vehicles are involved. 

The collision became a 'chain reaction' on the road, where whiteout conditions are being reported due to a winter storm that's hitting the south central part of the province. 

Injuries are reported — the extent is not yet known. 

More to come.
