WASHINGTON (AP) -- U.S. intelligence officials have
received threats that terrorists will strike a U.S. nuclear
power plant July 4, and are reviewing the information to
determine whether it is reliable.
The government is taking the threats seriously, though
officials have preliminarily determined that the information
is not credible enough to act upon, said officials familiar
with the investigation.
The officials, who spoke on condition of anonymity, said
the alleged plot to attack on America's celebration of
independence is one of scores of threats filtering through
U.S. intelligence and is not considered serious enough to
formally warn the public or change the nuclear industry's
already high level of alert.
The threat received last week suggested that an
unidentified Islamic terrorist group was planning to attack a
nuclear power facility in the Northeast, officials said. It
did not specify a target.
Unlike some other recent threat information, the power
plant threat did not come from Abu Zubaydah, the senior
al-Qaida operational leader in U.S. custody. Abu Zubaydah's
interviews with U.S. interrogators led a recent warning to
banks, and heightened concerns al-Qaida was developing a
radiation-spreading dirty bomb.
Rep. Edward Markey of Massachusetts, a senior Democrat on
the House Energy Committee, said that while he didn't know if
the threat was credible, it indicated that ``al-Qaida is
seriously targeting U.S. nuclear facilities for future
He said he is urging the Nuclear Regulatory Commission to
take such steps as restoring a no-fly zone within a 10-mile
radius of nuclear plants, federalizing the security force and
conducting more extensive background checks of all plant
