Members of Osama bin Laden's family were among the victims in the crash of a private jet in the UK yesterday, the Saudi embassy in London said in a message of condolences.
Four people died when the Saudi Arabia-registered plane crashed into a car auction site and burst into flames in Hampshire.
Local police said the pilot and three passengers died when the Phenom 300 jet attempted to land at Blackbushe Airport and that no one was injured on the ground.
The Saudi ambassador "offered his condolences to the sons of the late Mohammed bin Laden and their relations for the grave incident of the crash of the plane carrying members of the family at Blackbushe airport," read a statement posted on the embassy's official Twitter account.
It did not confirm the identities of those killed.
However Saudi media has reported that Osama bin Laden's sister Sanaa along with her husband and mother were killed along with the Jordanian pilot.
The embassy also said it would work with British authorities to investigate the incident and repatriate the bodies for burial in Saudi Arabia.
Osama bin Laden's father Mohammed was a construction industry magnate and his numerous descendants constitute a prominent family with wide-ranging business interests.
Mohammed bin Laden himself died in a plane crash in Saudi Arabia in 1967.
Osama bin Laden, former supreme leader of al-Qaeda, was shot dead by US special forces in Pakistan in 2011.
Saudi Arabia's General Authority of Civil Aviation said in a statement that the plane was registered in the Gulf state, and that it would work with British investigators to determine the cause of the crash.
It is believed that the aircraft had taken off from Milan's Malpensa airport in Italy.
