BROOKLYN - Investigations are ongoing to determine the cause of the collision between two fire engines on Saturday.

Engine 236 and Ladder 107 crashed into each other just one block from a call of a reported gas leak, injuring 13 firefighters.

One of the trucks skidded through a fence and into a neighboring yard, damaging the property.

One of the firefighters remains hospitalized after his foot was pinned, leaving him inside the truck for hours.
