Osama bin Laden’s son, Hamza bin Laden has reportedly married the daughter of the lead hijacker of the Sept. 11, 2001 terror attacks.

The late Al Qaeda leader’s half-brother Ahmad al-Attas told The Guardian that Hamza, who has said he wants to avenge his dead terrorist dad, married the daughter of Mohammed Atta, an Egyptian national who hijacked and flew the first plane that crashed into the World Trade Center.

Hamza bin Laden, officially designated a terrorist by the U.S., surprised his family by going to Afghanistan where he has become an Al Qaeda leader under Osama’s former deputy, Ayman al-Zawahiri, The Guardian reported Friday.
