CAIRO, Egypt (AP)- Osama bin Laden warned in an audiotape aired Thursday that his fighters are preparing new attacks in the United States but offered the American people a “long-term truce” without specifying the conditions.

The tape, portions of which were aired on Al-Jazeera television, was the first from the al-Qaida leader in more than a year. It came only days after a U.S. airstrike in Pakistan that targeted bin Laden’s deputy, Ayman al-Zawahri, and reportedly killed four leading al-Qaida figures, possibly including al-Zawahri’s son-in-law.
