U.S. intelligence analysts believe Al Qaida has rebuilt its operating capability to a level not seen since just before the 2001 terrorist attacks.
The conclusion suggests that the group that launched the most devastating terror attack on the U.S. has been able to rebuild despite nearly six years of bombings, war and other tactics aimed at crippling it.
Still, numerous government officials said they know of no specific, credible threat of a new attack.
The report will be discussed at the White House on July 12, 2007, as part of a broader meeting on an upcoming national intelligence estimate.
The officials names were not released because the report remains classified.
