The information contradicts reports last month that the Swiss team thought it was likely Arafat had been poisoned after finding polonium

The report handed to Suhrafatwill not be published, but the French public prosecutor's office said it concluded: "In sum, death was not due to poisoning with Polonium

7, 2013 (BBC) The late Palestinian leader Yasser Arafat may have been poisoned with radioactive polonium
, says a Swiss forensic report obtained by al-Jazeera.
She told Reuters the polonium

Summary: Swiss scientists have concluded Palestinian leader Yasser Arafat is likely to have died from polonium
poisoning, according to a text of their findings published by Al-Jazeera television Wednesday.
