The late al-Qaeda leader, Osama bin Laden had been the world's most wanted man since the 9/11 terror attacks on America in 2001. He was tracked down to a compound in Abbottobad, Pakistan, and killed on May 2 2011 in a raid by US special forces.

Taking to social media in a 21-minute rant video posted on Twitter, the terrorist's son, Hamza bin Laden vows to continue with al-Qaeda’s work.

 Hamzat says that the United States will be targeted in terror attacks similar to 9/11.

The footage was released by Al-Qaeda, and sees Hamza claim:

"We are all Osama”.

"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.

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

Hamzat is understood to now be aged 24.
