A White House official says nothing in the documents and computer files recently seized in al-Qaida raids indicates plans for an imminent attack on US financial buildings. But the official says some of the files showing surveillance of such buildings had been accessed this spring. That's months later than authorities had previously disclosed. The White House issued warnings on August first based on the surveillance of financial buildings in New York, Washington and New Jersey in 2000 and 2001. But the official says he's seen no indication of "an imminent operation." Investigators are still poring over volumes of the seized information. The administration remains concerned about other information that al-Qaida was plotting a major attack inside the US this summer to disrupt the elections.
