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.

The results of tests on Arafat’s remains “moderately support the proposition that the death was the consequence of poisoning with polonium-210”, said the 108-page analysis posted on Al-Jazeera’s website on Wednesday.

“New toxicological and radio-toxicological investigations were performed, demonstrating unexpectedly high-levels of polonium-210 and lead-210 activity in many of the analysed specimens.”
