The Bush administration yesterday put the United States on a high state alert, saying it had picked up credible intelligence of a possible terrorist attack "that could either rival or exceed" September 11.
It was unclear last night whether the decision to raise the state of alert was connected to a broadcast on Friday on the Arabic television network al-Jazeera - the station aired an audio tape of a statement attributed to Ayman al-Zawahiri, Osama bin Laden's deputy and an Egyptian-born al-Qaida strategist.
"We are still chasing the Americans and their allies everywhere, even in their homeland," Mr al-Zawahiri said on the tape.
