American al-Qaida militant Adam Gadahn urged Islamist militants to welcome President Bush with bombs when he visits the Middle East this week.

"Welcome him not with flowers and applause but with bombs and traps," he said in an Arabic aside on a 50-minute video posted on the internet on Sunday, which was mostly recorded in English and aimed at the American public.

Gadahn, who is also known as Azzam the American, devoted most of the tape entitled "An Invitation to Reflection and Repentance," to a detailed explanation of the shortcomings of U.S. foreign policy and Western Christian civilization and their defeat at the hands of Islam and Muslims.
