A soldier has died while taking part in a live-firing training exercise at night, Armed Forces Minister Mike Penning has said.
The male soldier, from the Royal Regiment of Scotland, was shot on Monday night on a firing range at the Otterburn Training Area in Northumberland.
Northumbria Police said the soldier died after suffering a "serious head wound".
The police and the Ministry of Defence are investigating. An MoD spokesman said there were no details on whether any other personnel were involved.
The spokesman said: "At around 11.15pm last night police received a report that a soldier had been shot on the military ranges in Otterburn during a live-firing exercise.
"Emergency services attended and found the male soldier had received a serious head wound. Sadly he was pronounced dead at the scene by paramedics.
"Police will be working with the Ministry of Defence to establish the exact circumstances of the incident and a cordon is currently in place. Military officials have informed the soldier's next of kin."
The MoD has not yet released the soldier's identity.
