A plane crash in southern Afghanistan has killed four members of the Nato-led International Security Assistance Force.
The identities of the four have not been released and it is not clear whether they were military personnel or civilians.
A Nato statement said: "The cause of the crash is under investigation, however initial reporting indicates there was no enemy activity in the area at the time of the crash."
There have been reports of fierce fighting in the north of the country.
Mohammad Jan Rasoulyar, deputy governor of the southern province of Zabul, told AP that an aircraft belonging to foreign forces crashed on Saturday afternoon in Shah Joy district. He confirmed the site had been surrounded by international forces.
