The five Nato service personnel killed in southern Afghanistan were involved in an apparent 'friendly fire' incident, the international coalition has said.
"The casualties occurred during a security operation when their unit came into contact with enemy forces. Tragically, there is the possibility that fratricide may have been involved. The incident is under investigation." Nato said in a statement.
A spokeswoman for the Ministry of Defence said they were not British personnel. Most of the forces operating in the area are from the United States.
