Questions Still Surround Diana's Death

August 31 -- (ABCNEWS.com) — On the fourth anniversary of the crash that claimed the life of Princess Diana and her companion, Dodi Al Fayed, Dodi's father, Mohamed Al Fayed, tells reporters he is continuing his quest for information on the tragic events that led to the deadly accident.

Shortly after the Aug. 31, 1997, crash that killed the couple, a French court determined that the cause was their intoxicated driver, Henri Paul — who also died in the wreck.

But Al Fayed has repeatedly accused British security services of engineering the crash to keep Diana, Princess of Wales, from marrying a Muslim, and he has filed lawsuits to force a number of U.S. agencies to release files he believes would prove this conspiracy. Al Fayed is the owner of London's famed Harrods' department store.

In a videotaped statement shown at a news conference in Washington, D.C., today, Al Fayed accused the agencies — which include the FBI, CIA, and National Security Agency — of stonewalling and vowed to continue his quest.

"They have done everything possible to delay the case and obstruct the release of documents which would show the corroboration between the United States and Parisian services and the British Secret Service," he said.

"I seek the support of the American people to bring pressure through the members of Congress to release the documents that will reveal the truth about the tragedy. I am in no doubt that the death was the result of a murder with racism at the core."

Al Fayed Says Marriage and Baby Were in Store Al Fayed's lawyers also presented several pieces of circumstantial evidence that supported the Egyptian tycoon's allegations.

In addition to believing that his son and the princess planned to be married, Al Fayed says that Diana was pregnant with his grandchild.

Diana's friends have dismissed both claims, but Al Fayed's representatives today presented research by a team of professionals designed in part to call for the release of Diana's postmortem report.
