Nato troops hunted down an Afghan policeman who shot dead two American soldiers this week, killing him with the help of intelligence tip-offs, the military said on Thursday.
Wearing a border police uniform, the man shot the soldiers inside a police compound on Monday while US military advisers were holding talks with a local colonel. The colonel later identified them as American.
The gunman fled, but was tracked down using "multiple intelligence reports" the Nato-led International Security Assistance Force (ISAF) said.
"A combined Afghan and coalition security force planned and conducted an operation today in Maimanah district, Faryab province, targeting the Afghan border policeman who killed two ISAF service members," ISAF said.
"The successful operation resulted in the death of the individual responsible for the shooting," it said. Two other suspected insurgents were detained for questioning, it added.
There are around 130,000 US-led international troops in Afghanistan fighting a nearly 10-year Taliban-led insurgency.
