The Al Qaeda terrorist organization has published a voice recording it claims belongs to Hamza Bin Laden, the son of arch-terrorist and Al Qaeda founder Osama Bin Laden.
The message is believed to be the first time Al Qaeda has presented Hamza Bin Laden as an official member of its organization.
In the recording published Friday and shared by the organization's supporters on Twitter, Hamza calls on followers to attack the United States as well as its allies, including Israel.
Preaching to "Al Qaeda faithful" in Kabul, Baghdad and Gaza, he urges followers to wage jihad, or holy war, on Washington, London, Paris and Tel Aviv.
The audio message also called "for the targeting of Jewish American interests globally."
In response, the national Jewish security arm founded by the Jewish Federations of North America warned Jewish institutions in the US to be on alert.
However, "there is no information at this time to suggest a credible or imminent threat as it relates to this audio message," the Secure Community Network said in its message.
Osama Bin Laden, Al Qaeda's founder and former leader, was behind the September 11 terror attacks in the United States. He was killed by US special forces four years ago during a raid on his compound in Pakistan.
Al Qaeda's former second-in-command, Ayman al-Zawahiri, has since taken control of the terrorist group.
Little is known about Bin Laden's son, Hamza, who is believed to be in his early to mid-twenties. He was born to Bin-Laden's third wife and was once designated to succeed his father.
Hamza's whereabouts are also unknown, with the last documented footage of him fighting alongside the Taliban appearing on Al-Jazeera during the US-led invasion of Afghanistan in 2001.
