The imam of the Garden Grove Mosque in Orange County, California, says that the American seen threatening the United States in the recent Al Qaeda videotape is indeed Adam Gadahn.

GARDEN GROVE, Calif.—The director of a California mosque told FOX Newson Friday he believes the man threatening the United States on a mysterious videotape is that of a young American he converted to Islam.

Haitham Bundjaki, the Orange County imam who converted Adam Yahiye Gadahn to Islam and whom Gadahn later assaulted, told FOX outside his mosque on Friday that it sounds like Gadahn on the tape.

The FBI believes the 25-year-old Southern Californian has possible ties to Usama bin Laden’s terror network Al Qaeda.

In the video, aired Thursday night by FOX News, a man wearing dark glasses and an Arab headdress wrapped around his face claims to be an American member of Al Qaeda and promises attacks that will make the streets of America “run red with blood.”

From the gestures and voice, Bundjaki told FOX outside his Garden Grove Mosque where Gadahn became a Muslim, “I believe it was Adam.”
