LONDON — Three relatives of the late al-Qaida leader Osama bin Laden were among four people killed when a private jet crashed on landing in southern England, British police confirmed Saturday.

The Hampshire Police force said formal post-mortems were still being conducted, but the victims were believed to be “the mother, sister and brother-in-law of the owner of the aircraft, all of whom are from the bin Laden family.” It said all three were Saudi nationals who were visiting Britain on vacation. The plane’s Jordanian pilot also died.

Arab media and NBC News named the relatives as Osama bin Laden’s stepmother Rajaa Hashim, his sister Sana bin Laden and her husband, Zuhair Hashim.

Saudi Arabia’s ambassador to Britain, Prince Mohammed Bin Nawaf Bin Abdel-Aziz, offered his condolences to the wealthy bin Laden family, which owns a large construction company in Saudi Arabia.

Police said the Embraer Phenom 300 executive jet crashed into a parking lot and burst into flames while trying to land at Blackbushe Airport in southern England Friday afternoon.
