A new al-Qaida videotape on the Internet shows an American member of the terror network calling for attacks on President Bush during his travels in the Middle East later this week.

In a 50-minute-long video that appeared Sunday in the name of al-Qaida's media group, Adam Gadahn denounces U.S. foreign policy as well as Arab leaders who are hosting Mr. Bush during his trip.

The U.S.-born Gadahn, who also calls himself "Azzam the American," urges militants to greet Mr. Bush with bombs, not flowers.

Gadahn also ripped up his U.S. passport on the video. He spoke mostly in English and wore the traditional attire of Gulf-region Arabs.

At the White House, U.S. national-security spokesman Gordon Johndroe said al-Qaida offers nothing but violence and death. Asked about Gadahn, the president's aide said the American's passport already was void, because he is wanted for treason.

Gadahn has appeared in several previous al-Qaida video releases, acting as a spokesman and advocate for the terror network. A U.S. court charged him with treason in 2006, and the FBI has a $1-million cash reward for information leading to his capture.

29-year-old Gadahn was raised in California, where he converted to Islam. He is believed to have been living in Pakistan for several years.
