The NATO-led International Security Assistance Force (ISAF) in Afghanistan says six of its troops have been killed in an insurgent attack in the south of the country.
An ISAF statement today did not give the nationalities of the soldiers or any further details.
Most NATO troops in southern Afghanistan come from the United States, but there are contingents from several other countries in the area.
Today's deaths are the bloodiest toll from a single incident for foreign troops since six soldiers were shot dead on November 29 by a renegade Afghan border policeman.
