Paris ( CNN ) -- Yasser Arafat 's widow on Tuesday questioned the findings of French scientists that the Palestinian leader did not die from radioactive polonium poisoning but rather from natural causes . The conclusion , leaked to multiple French media agencies and Reuters , contradicts the findings of Swiss forensic scientists who concluded last month that samples taken from Arafat 's exhumed body were consistent with polonium-210 exposure but did not definitely prove that he was poisoned . `` I 'm convinced there is something wrong , and he did not die from a natural death , '' Suha Arafat said at a news conference in Paris . She said she is requesting that the Swiss findings be made available to French authorities investigating her husband 's death . She said the medical experts in Switzerland and France came from different medical fields . `` I do n't doubt them . But they are different skills . They are different types of medicines , '' she said . The French findings will do little to quell the rumors that Arafat was poisoned . Arafat died at age 75 at a Paris military hospital in November 2004 after he had a brain hemorrhage and slipped into a coma . Palestinian officials said in the days before his death that Arafat had a blood disorder -- though they ruled out leukemia -- and that he had digestive problems . Rumors of poisoning circulated at the time , but Palestinian officials denied them . Two weeks after Arafat 's death , his nephew said medical records showed no cause of death . Nasser al-Kidwa , who was the Palestinian observer to the United Nations , said toxicology tests showed `` no known poison , '' though he refused to exclude the possibility that poison caused his uncle 's death . Polonium-210 made headlines in 2006 , when it was used to kill Alexander Litvinenko , a former KGB agent who came to Britain in 2000 after turning whistle-blower on the FSB , the KGB 's successor . In a deathbed statement from a London hospital , Litvinenko blamed Russia 's President Vladimir Putin , an accusation the Kremlin strongly denied . Palestinians who view Arafat as a symbol of resistance are also quite emotional about the suspicion he was poisoned . Arafat first led the Palestine Liberation Organization , which carried out attacks against Israeli targets , and then served as the leader of the quasi-governmental Palestinian Authority after parts of the West Bank and Gaza were returned to Palestinian control . He was considered one of the pioneers of what became known as `` television terrorism , '' high-profile attacks that targeted Israelis and made for big television stories . Arafat won the Nobel Peace Prize in 1994 , along with Israeli leaders Yitzhak Rabin and Shimon Peres , for their work on the Oslo accords in 1993 . The Oslo agreement was perceived at the time as a breakthrough that could lead to an independent Palestinian state and a permanent peace with Israel . But in 2000 , Arafat rejected an Israeli peace deal based on the Oslo deal . That led to a Palestinian uprising that lasted more than four years . Israel -- in retaliation for increased terror attacks on Israelis -- severely restricted Arafat 's movements , confining him to his West Bank compound in Ramallah in December 2001 . Sandrine Amiel reported from Paris , and Chelsea J. Carter wrote and reported from Atlanta .
`` He did not die from a natural death , '' Suha Arafat said Tuesday . She says the findings by French scientists contract those of Swiss scientists . The French findings conclude Yasser Arafat was not poisoned with polonium-210 . Last month , Swiss scientists said there was evidence of polonium in samples .
