The son of the late al Qaida leader Osama bin Laden has threatened revenge against the US for assassinating his father.
In a video released by al Qaida's media arm, As-Sahab, Hamza bin Laden tells Americans that they are accountable for the decisions of their leaders.
He says al Qaida will continue waging jihad, or holy war, against the US in response to its "oppression" of Muslims.
"If you think that your sinful crime that you committed in Abbottabad has passed without punishment, then you thought wrong," he says.
Bin Laden was killed in a May 2011 US raid at his compound in Abbottabad, Pakistan.
His son's whereabouts are not known.
Analysts speculate that he may be preparing to take over leadership of al Qaida.
