Hamza Bin Laden is emerging as a key leader of the Islamist militant group, US officials say.
He is thought to be based near the Afghan-Pakistani border.
In recent years, he has released audio and video messages calling on followers to attack the US and its Western allies in revenge for his father's killing.
In 2011, US special forces killed Osama Bin Laden in a compound in Abbottabad, Pakistan. He approved the attacks on the US on 11 September 2001, in which nearly 3,000 people were killed.
