An Afghan policewoman has shot dead a US military adviser inside Kabul police headquarters, Afghan officials say.

It is the first reported incident in which a female member of Afghanistan's security forces has opened fire on a Nato soldier.

The attacker has been detained. Officials say they suspect she has links with the Taliban.

There has been a rise in incidents in which foreign troops have been killed by Afghan troops or policemen.

In Monday's incident, officials say the woman - an officer at the interior ministry - came looking for the police chief at the heavily secured headquarters.

The US adviser was thought to have been on his way to a canteen when she shot him with her pistol.

More than 50 members of the Nato-led force in Afghanistan have been killed by male Afghan troops or police this year.

In September the US suspended training for local police recruits because of such "insider attacks".

It said it was carrying out checks on whether recruits had links to the Taliban.
