A purported audio tape by a member of Osama bin Laden's al Qaeda network promises more attacks against Americans and denying any links to the killing of a Shi'ite Muslim cleric in Iraq last month.
"We announce there will be new attacks inside and outside which would make America forget September 11th," an al Qaeda spokesman said in the tape broadcast by the Arabic television channel Al Arabiya. It identified the spokesman as Mr Abdel-Rahman al-Najdi.
The tape, dated September 3rd, comes a few days before the second anniversary of September 11th.
Some US and Iraqi reports suggested that al Qaeda was behind a car bomb attack that killed top Shi'ite cleric Mohammed Baqer al-Hakim and 83 others in the Iraqi holy city of Najaf last month.
"Those who killed Baqer al-Hakim are the Americans and Jews because they know that his loyalty is to Iran," the speaker added.
