Two teenagers have died after a car they were travelling in crashed into a tree while reportedly on the way to a Halloween party.
A 19-year-old man and an 18-year-old woman were pronounced dead at the scene in Perham Down, near Tidworth, when emergency crews attended on Friday.
Witnesses, including soldiers from a nearby barracks, pulled the occupants - wearing Halloween costumes and make-up - from a Renault Clio, according to a source.
Four others in the car when it came off the road at around 10pm also suffered injuries.
The source added several people inside the car were members of the armed forces, but the Ministry of Defence (MoD) was unable to confirm.
Two men, aged 19 and 27, were taken to the regional major trauma centre at Southmead Hospital in Bristol with life-threatening injuries.
A 29-year-old man suffered serious injuries, and the other occupant of the vehicle, a 20-year-old man, suffered minor injuries.
The road is expected to remain closed for most of Saturday for collision investigation and recovery work.
A spokesperson for Wiltshire Police said: “At approximately 10pm we responded to the road traffic collision involving a Renault Clio which had struck a tree after leaving the road.
“We regret to report that a 19-year-old man and an 18-year-old woman were pronounced dead at the scene.”
The MoD said it was aware of the incident but a spokesman said they could not confirm if members of the armed forces were involved.
He added: "We are aware of the incident. Wiltshire Police are investigating so we are unable to give further details at this time."
Dorset and Somerset Air Ambulance was called to the incident.
Fire crews from Dorset and Wiltshire and Rescue Service and Hampshire and Isle of Wight Fire and Rescue Service also attended.
The victim's next of kin have been informed.
