On Thursday, the day before the fourth anniversary of the Paris car crash that killed Princess Diana and Dodi Fayed, Dodi’s father, tycoon Mohamed Al Fayed, once again accused American security agencies of covering up the investigation into the deaths of the couple. The Egyptian-born owner of London’s luxury Harrods store said he had no doubt that Diana and Dodi died as a “result of murder with racism at its core.” Fayed has claimed repeatedly that the British Royal family wanted to prevent Dodi, a Muslim, from marrying Diana. Despite several lawsuits, Fayed said that the CIA, the National Security Agency and the FBI have refused to turn over documents that he thinks would substantiate his claim — a claim that the U.S. and British governments have repeatedly labeled as ludicrous. “We understand his grief and tremendous sense of loss, but any suggestion that the CIA spied on Dodi Fayed or Princess Diana or has knowledge of any plot to murder them . . . is totally unfounded,” an agency spokesman, Mark Mansfield, told Reuters. Meanwhile, an important and lasting reminder of Diana was furnished this week by the Diana, Princess of Wales Memorial Fund, which has announced a $7.2 million project to educate health workers in Africa and help ease the suffering of Africans dying of AIDS and other diseases. Meanwhile, Diana’s sons, William, 19, and Harry, 16, planned to remember their mother “in their own way,” said a St. James’s Palace spokesperson. Prince Charles spent the day on the Balmoral estate in Scotland, the royal family’s traditional August retreat.
