The two NATO soldiers killed Saturday by insurgents in Afghanistan were from Romania, Fox News has learned.

The Romanian soldiers were shot by two insurgents dressed in Afghan Army uniforms, Fox News reported, citing a U.S. defense official.

Other NATO troops returned fire and killed the shooters.

The shooting occurred at Kandahar Airfield, the official told Fox News.

NATO reported the deaths in a statement.

The statement said the victims were members of the Resolute Support international mission in Afghanistan. Their nationality was not mentioned.

According to the statement said that the shooters were two Afghans wearing the uniforms of the Afghan National Defense and Security Forces (ANDSF).

The statement identified the location of the shooting as an ANDSF compound in southern Afghanistan, without being specific.

After international forces wrapped up their combat mission at the end of 2014, Resolute Support was created with a coalition of international troops serving in a training and advisory role.
