Saudi Arabia has stripped Osama bin Laden's son Hamza of citizenship, after the US announced a $1m reward for help locating him.

A US State Department notice said bin Laden, reported to be 30 years old, had emerged as a leader of the al Qaeda terrorist group.

It is offering the cash as part of its "reward for justice" programme.

"Hamza is son of [Osama] bin Laden and has threatened attacks against the United States and allies.

"Relocation possible. Submit a tip, get paid."

Hamza bin Laden was named a "specially designated global terrorist" in January 2017, and has released audio and video messages calling for attacks against the US and its allies.

His father founded al Qaeda and was described as its spiritual leader.

The terror group was responsible for the September 11 attacks in the US that left 2,997 people dead in 2001.

Osama bin Laden was killed in a US military raid in Pakistan in May 2011.
