U.S. counterterrorism officials have authenticated a video by an al Qaeda recruiter threatening to smuggle a biological weapon into the United States via tunnels under the Mexico border, the latest sign of the terrorist group's determination to stage another mass-casualty attack on the U.S. homeland.
The video aired earlier this year as a recruitment tool makes clear that al Qaeda is looking to exploit weaknesses in U.S. border security and also is willing to ally itself with white militia groups or other anti-government entities interested in carrying out an attack inside the United States, according to counterterrorism officials interviewed by The Washington Times.
The officials, who spoke only on the condition they not be named because of the sensitive nature of their work, stressed that there is no credible information that al Qaeda has acquired the capabilities to carry out a mass biological attack although its members have clearly sought the expertise.
The video first aired by the Arabic news network Al Jazeera in February and later posted to several Web sites shows Kuwaiti dissident Abdullah al-Nafisi telling a room full of supporters in Bahrain that al Qaeda is casing the U.S. border with Mexico to assess how to send terrorists and weapons into the U.S.
"Four pounds of anthrax -- in a suitcase this big -- carried by a fighter through tunnels from Mexico into the U.S. are guaranteed to kill 330,000 Americans within a single hour if it is properly spread in population centers there," the recruiter said. "What a horrifying idea; 9/11 will be small change in comparison. Am I right? There is no need for airplanes, conspiracies, timings and so on. One person, with the courage to carry 4 pounds of anthrax, will go to the White House lawn, and will spread this 'confetti' all over them, and then we'll do these cries of joy. It will turn into a real celebration."
In the video, obtained and translated by the Middle East Media Research Institute, al-Nafisi also suggests that al Qaeda might want to collaborate with members of native U.S. white supremacist militias who hate the federal government.
Sean Smith, a spokesman for Homeland Security Secretary Janet Napolitano, said the U.S. takes such threats seriously.
"We can never stop being vigilant while there are individuals who seek to do harm on the American people," he said. "We continue to step up our efforts with additional personnel and better technology along the northern and southern borders and continue to strengthen our sea, land and air ports of entry."
