Osama bin Laden's 28-year-old son Hamza is being hunted in a "kill or capture" mission by Joint Coalition Special Operations Unit which includes UK special forces, according to British media reports.
Hamza has become active as an al-Qaeda propagandist since his father's death at the hands of US special forces in May 2011.
"A Joint Coalition Special Operations Unit, including 40 SAS soldiers, have reportedly been flown in to Syria on a covert mission to find Hamza and his gang," The Mirrror reported.
"He is now considered in the top 10 'high-value' targets being hunted by Coalition forces deployed on Operation Shader."
The United States added Hamza bin Laden to its terrorist blacklist in January.
The US Treasury estimates that he was born in 1989 in the Saudi city of Jeddah. His mother was Khairiah Sabar, one of the Al-Qaeda founder's three wives.
Last year, the fifth anniversary of the death of the man who ordered the 9/11 attacks on the United States, experts began to note his son's increasing prominence in the movement. The State Department has designated him a "Specially Designated Global Terrorist," freezing any assets he holds in areas under US jurisdiction.
Experts believe Hamza is preparing to take over the leadership of al-Qaeda and exploit ISIS defeats in Syria and Iraq to unify the global militant movement under the banner of al-Qaeda.
