KABUL, Afghanistan - Officials say violence in Afghanistan has left 18 dead, including two NATO soldiers and 14 insurgents.

A NATO statement says a soldier and civilian interpreter were killed when an explosion hit them during a patrol in eastern Ghazni province on Tuesday.

It says two NATO soldiers were wounded, one of whom later died at a military hospital.

The statement does not give any details about the victims' nationalities or the nature of the explosion.

In neighbouring Zabul province, deputy governor Gulab Shah Alikhel says air strikes and a three-hour gun battle killed an Afghan army soldier and 14 insurgents. He says six of the dead insurgents appear to be Arabs.

Afghan security forces seized insurgents' ammunition and night vision goggles.
