Ban Dung (Thai: บ้านดุง, pronounced [bâːn dūŋ]) is a district (amphoe) in northeastern Udon Thani province, Isan, Thailand.

It will have sufficient power to reach the Middle East and the West Coast of the United States, both areas with large expatriate Thai communities.

[6][7] That suspicion has been supplanted by a BBC report that the Udon Royal Air Force Base was the home of a CIA black site, known to insiders as "Cat's Eye", but better known as "Detention Site Green",[8] used to interrogate Abu Zubaydah, a 31-year-old Saudi-born Palestinian, believed to be one of Osama bin Laden's top lieutenants.

In December 2014 the United States Senate Select Committee on Intelligence (SSCI) published an executive summary of a secret 6,000-page report on CIA techniques.

Ban Dung district is also the largest source of rock salt production in the Isan from the past to the present.
