New York ? A tape delivered to ABC News in Pakistan this weekend features a masked man making terrorist threats against Los Angeles and Australia.

ABC News reported that the man is believed to be Adam Yahiye Gadahn, an American from California purported to be an al-Qaida member and wanted by the FBI. The CIA said Sunday it was aware of the report but had no immediate comment about the tape’s authenticity.

Counterterror officials believe Gadahn also may be the person on a 75-minute video given to ABC News last year in Pakistan.

The latest tape was aired on ABC’s “Good Morning America” on Sunday, the fourth anniversary of the Sept. 11 attacks. The man on the tape, wearing a black turban with most of his face covered, calls the attacks of four years ago “blessed events” before making a threat against the U.S.

“Yesterday, London and Madrid. Tomorrow, Los Angeles and Melbourne, Allah willing. And this time, don’t count on us demonstrating restraint and compassion,” the man says during the 11-minute tape.
