A U.S. counterterrorism official said, "There's never been a fake Bin Laden tape. In the past, he has timed the release of messages to major events, so it's unsurprising that he chose this particular week. While the words are different, this latest message recycles many of the broad themes of messages past. While people are still reviewing the message thoroughly, there's no reason at this point to believe that any specific or credible threat is contained in it."
