It seems, the Al-Qaeda's role in Terrorism did not come to an end, even after Osama bin Laden, the mastermind behind 9/11 attacks, was killed by U.S. Navy SEAL at Pakistan in 2011.
The U.S state department tagged Osama bin Laden's son, Hamza bin Laden as "Specially Designated Global Terrorist". This designation, according to the department, "imposes sanctions on foreign persons determined to have committed, or pose a serious risk of committing, acts of terrorism that threaten the security of US nationals or the national security, foreign policy, or economy of the U.S".
Reportedly, Hamza bin Laden has been included in the watchlist, after he threatened terror attacks against the US. Sa'ad bin Laden is the first son of Osama, who was killed in 2009 and Hamza is the second one, who's now targeted by the U.S.
