Osama bin Laden’s son has issued a series of chilling messages threatening the Saudi royal family in a bid to become the future leader of al Qaeda, it has been reported.

Axar.az reports citing Metro news agency that Hamza bin Laden has issued two video messages in the past year; the first praising lone wolf attacks while calling for an uprising in the kingdom, and the most recent accusing its founder, Abdul-Aziz bin Rahman Al Saud, of being a British agent.

The second of the video messages were released by the terror group’s media arm, as-Sahab, from its hideout in Pakistan, according to al Monitor.

In it, he claims that the Saudis have betrayed Islam by working with the ‘crusaders’ against the Ottoman caliphate.

It is not the first time that Hamza, believed to be 28, has appeared in a propaganda message for al Qaeda and has previously called for terror attacks in London, Washington and Paris.

Earlier this year he was placed on the US State Department’s terror watch list and labeled a ‘specially designated global terrorist’.

The authority attributed a number of audio messages to Hamza in which he attacks the west and threatens revenge against the United States.

According to FBI agent Ali Soufan, Hamza uses the same terminology as his father.

He told CBS that Hamza has been seen as the next leader of the terror organization since he was a child.

“He was a poster kid for the al Qaeda…and for members of al Qaeda, who were indoctrinated with these propaganda videos, he means a lot to them,’ Soufan said.
