Three members of former Al Qaeda chief Osama Bin Laden's family were killed in southern England after a private plane crashed on Friday.

Reports confirmed that the private jet with a Saudi registration was carrying three close family members of the former Al Qaeda chief. All four people onboard the plane, including the pilot, were killed, British police told Reuters.

The sister and stepmother of the former al-Qaida leader Osama bin Laden were reportedly among the dead in the Hampshire plane crash, The Guardian reported.

Without revealing of identities of the plane crash victims, Saudi Ambassador to UK, Prince Mohammed bin Nawaf Al Saud, offered condolences on the embassy's official Twitter account to the bin Laden family, which is a prominent Saudi clan with vast business interests.

"His royal Highness Prince Mohammed bin Nawaf bin Abdul Aziz, the ambassador of the Custodian of the Two Holy Mosques to the United Kingdom, 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 Balckbushe airport," he said in the tweet.

It is reported that Embraer Phenom 300 jet crashed while landing at the Blackbushe Airport, an airfield used by private planes, located 65 km from London. Videos of the crash shared on social media shows that the plane crashed into a car auction centre.

The official Saudi Press Agency-SPA confirmed that the plane was Saudi-owned and has entered UK from Milan.
