East of England Ambulance Service NHS Trust spokesman Gary Sanderson, who attended the scene where three men believed to be in their late teens and early 20s died after their car and an articulated lorry collided, said:
First and foremost our thoughts are firmly with all of the families of the men involved in this tragic incident.
Following a rapid scene assessment by paramedics at the scene, three men were pronounced dead shortly after. A fourth man, who was seriously injured, was treated by land and air ambulance crews, before he was flown to the Royal London Hospital in Whitechapel for further care.
Anyone with information is asked to contact police on 101.
