Suspicions that the former Palestinian leader Yasser Arafat was poisoned will be strengthened by the discovery by Swiss scientists of 18 times the normal level of radioactive polonium in his remains. But his death remains a whodunnit.
Arafat, who had long symbolised the Palestinians' fight for their own state, died on November 11, 2004, from an illness that was never fully diagnosed by his doctors. Swiss scientists have been carrying out tests on tissue taken from Arafat's body and personal items.
They say they are confident up to an 83 per cent level that he was poisoned and suspect that the cause may be polonium. The results are contained in an 108-page report by the University Centre for Legal Medicine in Lausanne which was obtained by Al Jazeera which had previously carried out its own inquiry.
Arafat's body was exhumed last November in Ramallah on the West Bank and 60 tissue samples were given to Swiss, French and Russian teams of forensic scientists.
Dave Barclay, a British forensic scientist and former detective, told Al Jazeera that the findings had convinced him that Arafat had been murdered. "Yasser Arafat died of polonium poisoning. We found the smoking gun that caused his death. The level of polonium in Yasser Arafat's rib ... is about 900 millibecquerels. That is either 18 or 36 times the average, depending on the literature."
