The Palestinian Authority accused Israel on Friday of being a "prime suspect" in the death of Yasser Arafat, after results from a Swiss investigation found high-levels of radioactive polonium on Arafat's remains, AFP reported.
At a press conference, Palestinian officials said the Swiss report shows Arafat did not die from old age or ill health, nor did he die of natural causes.
Prof. Francois Bochud of the Swiss investigation team told a news conference on Thursday that while the high level of polonium detected indicated on involvement of a third party, the results only offer moderate backing of the theory of poisoning.
"Was polonium the cause of the death for certain? The answer is no, we cannot show categorically that hypothesis that the poisoning caused was this or that," he added.
