The Taliban have announced they will release a new video of a U.S. soldier captured in Afghanistan, a U.S-based terrorism monitoring group said Wednesday.

SITE Intelligence Group, a U.S.-based terrorist tracking organization, said the media arm of the Afghan Taliban made the announcement Wednesday on their Web site.

The video is said to be titled, "One of Their People Testified." The Taliban did not name the American.

The only U.S. soldier known to be in captivity is Pfc. Bowe Bergdahl of Hailey, Idaho, who disappeared more than five months ago in Afghanistan.

Bergdahl, 23, was captured June 30 in the eastern province of Paktika province near the Pakistan border. His Taliban captors released a propaganda video of him about two weeks later. In the July 19 video, Bergdahl appeared downcast and frightened. No subsequent videos have been released.

U.S. military officials have searched for Bergdahl, but it is not publicly known whether he is even being held in Afghanistan or neighboring Pakistan.

Pakistan is off-limits to the thousands of U.S. forces based in Afghanistan. When militants captured a reporter for The New York Times in a dangerous region of Afghanistan last year, he was transported to Pakistan and held for months there. The reporter, David Rohde, eventually escaped.
