Two die in Afghan 'insider attack'
Two Nato troops have been killed in an apparent insider attack in southern Afghanistan.
A man wearing an Afghan police uniform opened fire on them in the latest in a string of killings that have threatened to sever the partnership between international troops and the Afghan forces they are trying to train to take over responsibility for the country’s security.
There have also been cases of insurgents donning Afghan uniforms in assaults.
Nato said the shooting was still under investigation.
At least 53 international troops have been killed in confirmed attacks by Afghan soldiers or police this year, and a number of other assaults are still under investigation.
