It was an extremely busy city back then".

The BBC has reported that Udon Thani's Royal Air Force Base was the site of a CIA black site, known to insiders as "Detention Site Green", used to interrogate Abu Zubaydah, Saudi-born Palestinian, believed to be one of Osama Bin Laden's top lieutenants.

The report alleges that at least eight Thai senior officials knew of the secret site. The site was closed in December 2002.

Earlier reports alleged that a Voice of America relay station in a rural area of Udon Thani Province, Ban Dung District, was the CIA black site.
