The Post on Ridge's Orange Alert: The federal government raised the terror alert level yesterday to orange for the financial services sectors in New York City, Washington and Newark, citing the discovery of remarkably detailed intelligence showing that al Qaeda operatives have been plotting for years to blow up specific buildings with car or truck bombs. Homeland Security Secretary Tom Ridge said the newly acquired information points to five potential targets: 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.
