UK troops kill Afghan civilians
The incident took place in the Sangin district of Helmand
British troops in southern Afghanistan have killed four civilians and injured three others after a vehicle failed to stop at a checkpoint.
Soldiers opened fire on the vehicle in the Sangin district of Helmand, suspecting that those inside were insurgents, Nato said.
The wounded Afghans were taken to a field hospital at the UK's Camp Bastion for treatment.
The International Security Assistance Force expressed regret at the incident.
However, it said the situation had been "caused by the reckless actions of the vehicle driver''.
The BBC's Alistair Leithead said it had been a "bad week" for troops at the nearby Inkerman base, where the Afghans were initially taken for treatment.
A dog handler was killed after a patrol came under attack from the Taleban and a soldier was injured when a British mortar bomb fell short.
