The video of Warren Weinstein appeared Wednesday on jihadi sites, CNN reported, quoting the SITE Intelligence Group, which monitors the online activities of militant groups.
Weinstein was shown in the video asking Israeli Prime Minister Binyamin Netanyahu to intervene and meet al-Qaida's demands in exchange for his freedom.
Weinstein, who was working in Pakistan as a development expert representing a Arlington, Va., consulting firm, was abducted in August 2011.
The video quoted him as saying the U.S. government has "no interest" in his case, CNN reported, quoting SITE.
"Therefore, as a Jew, I am appealing to you, Prime Minister Netanyahu, the head of the Jewish state of Israel, as one Jew to another, to please intervene on my behalf, to work with the mujahedin and to accept their demands so that I can be released and returned to my family, see my wife, my children and my grandchildren again," Weinstein was quoted as saying.
CNN said in an earlier video, Weinstein was shown making a plea to U.S. President Barack Obama but the U.S. government, while expressing sympathies for the kidnapped victim and his family, had said it would not bargain with al-Qaida.
