Sunday August 31 4:30 PM EDT World Mourns Princess Diana By James Anderson LONDON (Reuter) - From heads of state to the man in the street, from Nobel laureate Mother Teresa to opera superstar Luciano Pavarotti to the ordinary London cabbie, tributes to Princess Diana poured in Sunday as the world mourned her untimely passing. Anger mounted, meanwhile, against the pursuit by photographers on motorcycles which was widely blamed for the car crash in which she and her companion, millionaire Dodi Al Fayed, died. As piles of flowers grew outside Kensington Palace, her London home, the Salpetriere Hospital in Paris where she died and the tunnel beside the River Seine where her car crashed, Diana's brother said every press owner and editor who paid for the hysterical chase for her picture "has blood on his hands." World leaders paid tribute, calling the divorced wife of the heir to the British throne "The People's Princess" and a woman "warm, full of life and generosity." So did charity workers whose causes were blessed with her image -- the sad and beautiful "Lady Di," whose eyes spoke more than words could say of compassion for the sufferers from AIDS and the victims of land mines. In death she even transcended the sectarian violence in Northern Ireland as Catholic supporters of the province's union with the Irish Republic and stalwarts of continued British rule mourned the passing of a great humanitarian. In St. Paul's Cathedral 2,000 people gathered to remember her Sunday evening at a service in the church where she was married in a glittering royal ceremony 16 years ago. Diana died as representatives of about 100 countries were gathering in Oslo to try to draft a treaty banning anti-personnel landmines. "We lost our greatest supporter of banning the mines," Aziz Ahmad of the British mine-clearance agency the Halo Trust told Reuters in Kabul, the capital of war-ruined Afghanistan. "My whole family is crying," 37-year-old Plamenko Priganica, a former Bosnian soldier who lost his leg from a mine blast, said in Tuzla, where the princess visited last month to publicise her favorite cause. Mother Teresa, the 87-year-old nun revered for her lifelong work to help the unfortunate, said in Calcutta Diana was "a very great friend in love with the poor." In a rare note of hostility to everything the princess stood for, the state television of Islamic Iran reported that "One of the elements of moral disgrace in the British court has been killed in a car accident in France." Hailing Diana as "the people's princess," British Prime Minister Tony Blair said: "The whole of our country, all of us, will be in a state of mourning. Diana was a wonderful, warm and compassionate person who people, not just in Britain, but throughout the world loved and will be mourned as a friend." President Clinton told reporters covering his three-week family vacation on Martha's Vineyard: "We liked her very much. We admired her work for children, for people with AIDS, for the cause of ending the scourge of land mines in the world, and for her love for her children, William and Harry." But Clinton declined to rush to judgement on the media. "I think it is better right now if we let a little time pass and let this event and the people involved be honored and grieved. Then we'll have time to think about that and maybe make a better judgement." Wherever Diana's admirers gathered, however, red-eyed and speechless, at places associated with her life and her death, newsmen were heckled and booed. A policeman marching a photographer out of the garden near her home said: "We are worried about a breach of the peace and we want them out of the gardens for their own safety." Patients and staff at the Salpetriere Hospital in Paris shouted "murderers" at journalists covering the arrival of Prince Charles to collect Diana's body. Celebrities and public figures blaming the media for her death ranged all the way from singer Pavarotti and Hollywood actor Tom Cruise to German Chancellor Helmut Kohl. "Princess Diana has become the victim of an increasingly brutal and unscrupulous competitive fight of a section of the media," Kohl said. "This terrible accident and her death should finally give those responsible in the media something to think about." More bitter still were the words of Diana's brother. "I always believed the press would kill her in the end," Earl Spencer told reporters outside his house in Cape Town in South Africa. "Not even I could imagine that they would take such a direct hand in her death, as seems to be the case. "It would appear that every proprietor and editor of every publication that has paid for intrusive and exploitative photographs of her, encouraging greedy and ruthless individuals to risk everything in pursuit of Diana's image, has blood on his hands today." Tributes flowed in from as far afield as Japan's Prime Minister Ryutaro Hashimoto and Cambodia's King Norodom Sihanouk to Russian President Boris Yeltsin to South African President Nelson Mandela and Israeli Prime Minister Benjamin Netanyahu. But it was the ordinary poeple who turned out in droves at key sites that marked her life. Red-eyed and speechless, hundreds of mourners gathered at her London home to pay tribute. Bouquets of late summer blooms carpeted the path leading up to the elegant Kensington Palace, Diana's home since her marriage to Prince Charles collapsed, while other bunches were pushed through the wrought iron and gold filigree gates. "It's the only gesture we felt we could make," said Jean Watson, in London on a day trip from the Northern town of Preston, as she laid a bunch of roses outside the gates. Britain's diverse ethnic mix was well represented in the crowds with many Londoners of Asian and Caribbean descent turning up to pay tribute. "She was different from the rest. She was the only one of the royals who you felt was in touch with things," said one dreadlocked mourner who admitted he would not have come to pay tribute if Queen Elizabeth II or her aged mother had died. "I think all countries feel they have lost a very good human being. She was the Queen of Hearts," said London taxi driver Izi Dagan. Israel-born Dagan left a bunch of flowers at Buckinhgam Palace, adding to a collection of simple bouquets, lighted candles and hand-written messages. British broadcasting networks dropped regular programs on Sunday to bring wall-to-wall news coverage of the death. News bulletins on the BBC were introduced to the strains of the National Anthem. Black-tied news readers sombrely updated a grieving public. The world of sport also joined in the day of mourning. A premier league soccer clash between Liverpool and Newcastle was postponed and rugby league matches were starting with moments of silent tribute.
