KANDAHAR: An Afghan army soldier killed at least one Nato soldier on Saturday, near the southern Afghan city of Lashkar Gah, due this week to be one of the first places where Nato will hand security control to Afghan forces, a senior police source said.

“The shooting happened during a joint security patrol,” said the senior police detective, who asked not to be named as he was not authorised to speak to the media.

The Nato-led International Security Assistance Force said it was investigating an incident in southern Afghanistan.

“An individual wearing an Afghan National Army uniform turned his weapon against International Security Assistance Force service members in southern Afghanistan today, killing one service member,” ISAF said in a statement.
