Two soldiers with the NATO-led International Security Assistance Forces (ISAF) were killed on Monday in a shooting incident in Afghanistan's northern Faryab province, 425 km northwest of capital city of Kabul, the military alliance said.

"Afghan and International Security Assistance Forces are investigating a shooting incident in Faryab province today that led to the deaths of two ISAF service members," said a statement issued here by ISAF.

The statement said that based on initial reporting, "An individual in an Afghan Border Police uniform fired on the ISAF members inside a compound,"

According to the statement the attacker after firing shots fled the scene.

"More information will be released as it becomes available." the statement added.

However, it did not reveal the nationalities of the victims, saying it is ISAF policy to defer casualty identification procedures to the relevant national authorities.

More than 140,000 ISAF soldiers with majority of them Americans have been stationed in Afghanistan.
