Police have maintained a strong presence at a Highland military base where a soldier was last night shot dead.
It is understood the man, believed to be from 3 Scots which are based at Fort George, near Inverness, had been out on a live firing exercise when he was killed.
Ambulance crews remained at the scene for several hours and army chiefs and police also attended.
Staff were kept within the base so they could be questioned by detectives.
Officers shut down the roads surrounding the area, with a car guarding the entrance to the site late into the night.
A police spokesman said: “Police along with Scottish ambulance service personnel attended where there was found to be one person fatally injured.
“There were no other casualties as a result of the incident and next of kin have been informed by police.
“Police Scotland is leading the investigation to establish the full circumstances of this incident and is working closely with the armed forces.
“This was a contained incident and there was no threat to the public.”
The Tain range is used by the British Army, the Royal Navy and the RAF as well as the US Air Force and other Nato air forces for bombing and strafing practice.
Typhoons and Tornados from RAF Lossiemouth are the main users of the range.
A Ministry of Defence spokesman said: “We will release more information as and when it becomes available. It would be inappropriate for us to comment further at this point.”
First Minister Nicola Sturgeon sent her condolences to the family of the person who died..
She said: “This is a tragic incident and my deepest condolences go to the family, friends and colleagues of the person who has died.
“It is another important reminder of the often difficult and dangerous job our armed forces do every day.”
