Yeah I know we knew it, but here it is, and was on Countdown.
http://www.msnbc.msn.com/id/5087301/But terrorism experts tell NBC News there's no evidence a credible al-Qaida spokesman ever said that, and the claims actually were made by a largely discredited group, Abu Hafs al-Masri Brigades, known for putting propaganda on the Internet.
“This particular group is not really taken seriously by Western intelligence,” said terrorism expert M.J. Gohel of the Asia-Pacific Foundation, an international policy assessment group. “It does not appear to have any real field operational capability. But it is certainly part of the global jihad movement — part of its propaganda wing, if you like. It likes to weave a web of lies; it likes to put out disinformation so that the truth is deeply buried. So it is a dangerous group in that sense, but it is not taken seriously in terms of its operational capability.”
The group has claimed responsibility for the power blackout in the Northeast last year, a power outage in London and the Madrid bombing. None of the claims was found to be credible.
"The only thing they haven't claimed credit for recently is the cicada invasion of Washington,” said expert Roger Cressey, former chief of staff of the critical infrastructure protection board at the White House and now an analyst for NBC News. Cressey also served as deputy to former counterterrorism chief Richard Clarke.
