HONG KONG: Al-Qaeda released a Sept. 11 anniversary video declaring that the United States was at war with Islam and that American Muslims should brace for a “holocaust,” U.S. monitors said Wednesday.

The video, which features Al-Qaeda leader Ayman al-Zawahri as well as its American spokesman Adam Gadahn, is entitled “Truth has Come and Falsehood has Perished” and was posted on jihadist forums, according to SITE and IntelCenter.

According to a SITE transcript, Gadahn rejects President Barack Obama’s assertion that the United States is not at war with Islam because “America is crystal-clear about its opposition to Islam as a political system.”

Referring to U.S. drone strikes, he says: “Today, American Muslims are being killed in Yemen, tomorrow they’re going to be killed [by the U.S. government] in New York and Los Angeles. Get ready for the holocaust.”

The video, which also features Al-Qaeda officials Ustadh Ahmad Farooq and Maulvi Asim Umar, also argues that the U.S. is facing defeat on various battlefronts, according to the monitors.

It totals more than 90 minutes in Arabic, English and Urdu, and comes a day after Zawahri issued a video eulogizing Abu Yahya al-Libi, his late deputy and propaganda chief who was killed in a drone strike in June.

Gadahn, also known as Azzam the American, was born in 1978. He is a California native and has appeared in several Al-Qaeda videos since 2004.

Egyptian Zawahri took charge of the extremist group following the death of Osama bin Laden, who was killed by U.S. special forces in May 2011.
