At least two people are dead, and several others are injured after a multi-vehicle crash on the westbound 10 Freeway in Ontario on Monday morning.

The Ontario Fire Department said crews responded to a crash involving multiple vehicles between Euclid and Fourth Street shortly before midnight. The initial call was for 25 possible patients. 

Three fire engines, one fire battalion and four ambulances responded to the scene. Firefighters helped transport one patient in critical condition, one in moderate and two were pronounced dead at the scene.
