The U.S. and its allies continue to be the prime targets of Al Qaeda militant group, warns Osama bin Laden's son, Hamza, in a recently released audio message.

"We will continue striking you and targeting you in your country and abroad in response to your oppression of the people of Palestine, Afghanistan, Syria, Iraq, Yemen, Somalia and the rest of the Muslim lands that did not survive your oppression," said Hamza, according to the SITE Intelligence Group.

The son, who is in his mid-20s, delivered his speech "We Are All Osama" in a 21-minute audio message released through Al Qaeda's media channel, As-Sahab.

He added, "As for the revenge by the Islamic nation for Sheik Osama, may Allah have mercy on him, it is not revenge for Osama the person but it is revenge for those who defended Islam."

Osama's son became known to public when the militant group's new chief Ayman al-Zawahiri introduced him through an audio message released last year. It is widely believed that the militant group aims to regain stronghold and inspire new recruits by grooming Hamza to become its new leader.

This won't be the first time the young bin Laden, already dubbed as "Crown Prince of Terror," addressed the world to incite terrorism. Last year, Al Qaeda released an audio message where he also spoke to inspire lone wolf attacks particularly on America and allies such as London, Washington, Paris and Tel Aviv.

"AQ leadership wants Hamza as a future leader: someone loved & inspirational, without a negative reputation or participation in infighting," tweeted Rita Katz, director of SITE.

In a series of tweets, Katz stated that Hamza has spent a considerable part of his young life marked by jihad and the creation of the militant group led by his late father in Afghanistan.

Osama died in 2011 when U.S. commandos attacked his hideout in Abbottabad, Pakistan. Hamza reportedly escaped while one of his brothers, Khalid, died during the surprise attack.
