Swiss scientists concluded Arafat death due polonium poisoning according to a text of their findings published by Al-Jazeera television on Wednesday.
The results of tests on Arafat’s remains ” fairly support the proposition that the death was the result of poisoning with polonium-210,” said the 108-page analysis posted on Al-Jazeera’s website.
“New toxicological and radio-toxicological probes were executed, demonstrating circumstantially high levels of polonium-210 and lead-210 activity in many of the analysed examples,” said the report penned by 10 experts at the Vaudois University Hospital Centre (CHUV).
It added that polonium levels in “bones and soft tissues were up to 20 times larger” than hypothesized, firmly ruling out the possibility previously reported in some media that passive smoking had caused greater than normal polonium levels on Arafat’s personal effects.
Some 60 samples were taken from the remains of the late Palestinian leader in November last year for a probe into whether he was poisoned by polonium.
The samples were divided between the Swiss and Russian investigators and a French team carrying out a probe at the request of Arafat’s widow.
Arafat died in France on November 11th 2004 at the age of 75, but doctors were unable to specify the cause of death. No autopsy was carried out at the time, in line with his widow’s request.
His remains were exhumed in November 2012 and samples taken, partly to investigate whether he had been poisoned — a suspicion that grew after the assassination of Russian ex-spy and Kremlin critic Alexander Litvinenko in 2006.
Arafat’s widow Suha said in an interview aired by Al-Jazeera that the poisoning, if proved, amounted to “the assassination of a great leader” and a “political crime.”
“I don’t know who did it, but it’s terrible,” she said.
The Palestinian official in charge of the investigation into Arafat’s death, Tawfiq Tirawi, said on Tuesday that he had received the findings of the Swiss laboratory, although he declined to disclose them.
Official Palestinian news agency WAFA said that a separate Russian team appointed by the Palestinian Authority also handed in its report on November 2.
Reacting to the Al-Jazeera report, a Palestinian source close to the probe told AFP that “the report contained information about high levels of polonium in the example that was tested,” but gave no further details.
