Two reports of alleged terrorist activity trigger fear in the US. White powder is discovered on Pennsylvania Avenue, just outside the White House. A section of central Washington DC is subsequently cordoned off by police and an all-points terror alert is issued. After this large-scale reaction, the powder is found to be harmless and a Homeland Security spokesman declares the powder to be “benign.” Later, ABC News cites an anonymous intelligence source who warned of an “imminent credible threat” in Manhattan from a “woman suicide bomber.” This news causes the stock exchange to dip, despite a rapid denial by police.
