    The FBI Joint Terrorism Task Force plans to interview hundreds of people whose travel patterns may match those of terrorists, officials said Saturday. Intelligence collected from overseas suggested that the suspected attackers are three men who traveled from the U.S. to Pakistan. Officials stress that the questioning is precautionary and will be used to rule people out—especially when they are not even sure the suspects entered the U.S. at all. New York remained on high alert Saturday due to the threat and the anniversary of the September 11 terrorism attacks, although law-enforcement officials insisted they had thoroughly investigated and ruled out a suspected car-bomb plot.
