Based upon detailed intelligence that showed al Qaeda plots to
blow up specific buildings with car bombs, the federal government
has learned that terrorists studied every aspect of those buildings
in the financial services sectors of New York, Washington and
Newark, N.J., including the thickness of window glass.
Based on the information the federal government raised the terror
alert level yesterday to orange. The potential targets are the
International Monetary Fund and World Bank Headquarters in Washington;
the New York Stock Exchange and Citigroup Center in New York;
and the Prudential Financial Building in Newark.
According to an article in today's Washington Post, the intelligence
"shows that al Qaeda has been methodically casing those buildings,
and perhaps others, since well before the September 11, 2001,
attacks on the Pentagon and World Trade Center
The article reported that the surveillance included details ranging
from the location of security desks and cameras in the buildings
to "what kinds of explosives would do the most damage to
the structures." The article went on to state, "the
operatives focused on structural features of the targets that
might 'prevent the buildings from toppling down,' including the
thickness of window glass."
