Two service men with the NATO-led International Security Assistance Force (ISAF) died following a small-arms fire attack in northern Afghanistan Sunday.

A press release issued by the ISAF confirmed the casualties but failed to disclose details.

Earlier the day, local police in northern Afghanistan's Baghlan province told Xinhua that an ISAF convey was attacked by insurgents' light-arms fire.

The ISAF forces returned fire, killing one insurgent.
