Afghan driver kills Spanish police
Two Western police trainers have been shot dead by their Afghan driver during a training session in the west of the country.
The gunmen was then killed by colleagues of his victims, members of the Spanish Civil Guard in Afghanistan to instruct local officers.
The attack in Badghis province, which also killed a local interpreter, appeared to be the latest in a series by infiltrators linked to the insurgency.
Spanish Interior Minister Alfredo Perez Rubalcaba said: "I can't say if the Taliban were behind this or not. But what is clear is that it was a premeditated attack.
"The person who opened fire knew exactly what he was doing. Therefore, this was a terrorist attack."
He said the shooter was the regular driver of one of the dead Spaniards and was not actually a policeman himself. The man had worked with the Spanish police unit since it arrived in Afghanistan five months ago, he said.
The officers, both 33, were members of the Civil Guard, the a paramilitary unit under the command of the Interior Ministry. Their translator was a Spanish citizen of Iranian origin.
Nato said the shooting of the Spanish officers came during a "mentoring session" between its forces and the Afghan police.
Intentional shootings by Afghans against coalition partners are a growing concern for the tens of thousands of foreign forces spread across Afghanistan.
Two American civilians and two Afghan soldiers were killed last month when an Afghan soldier who trained others at a base outside the northern city of Mazar-e-Sharif started shooting during a weapons exercise.
