An American member of al-Qaeda has warned the U.S. will face an attack worse than 9/11 unless it ends all involvement in Muslims lands. In a video released Tuesday, California native Adam Yahiye Gadahn, known as Azzam al-Amriki, calls on President Bush to withdraw all U.S. military and spies from Islamic countries, free all Muslims from U.S. jails and end support for Israel. Gadahn is wanted in the U.S. on charges of treason.
