London (CNN) Three members of Osama bin Laden's family were among four people killed in a small plane crash in southern England, British police said.

The plane crashed Friday at a car auction site on the property of Blackbushe Airport in Hampshire, to the west of London, Hampshire fire and rescue services said.

Three passengers and the pilot died. Among those killed were three members of bin Laden's family, described as the mother, sister and brother-in-law of the plane's owner, Hampshire police said.

Police named neither the victims nor the plane's owner. The bin Laden family members were visiting the United Kingdom on vacation, police said.
