Firefighters were called to a road traffic collision on the North Circular in Cricklewood.
A car collided with a pedestrian overbridge. Sadly three men died at the scene and two men were taken to hospital by London Ambulance Service crews.
Assistant Commissioner Pat Goulbourne said: "This was a tragic incident attended by our specialist crews who attended alongside our blue light partners to make the scene safe."
One of the Brigade's Fire Rescue Units was in attendance at this incident. They provide a core set of specialist skills, including difficult access, heavy cutting and extended duration breathing apparatus capabilities. The heavy cutting capability is particularly important in supporting some of the road traffic collisions the Brigade attends.
The Brigade was called at 2335 and the incident was over for firefighters by 0104. Two fire engines and a fire rescue unit from Hendon and Wembley fire stations attended the scene.
