Swiss scientists say the late Palestinian leader Yasser Arafat had ingested radioactive polonium, most probably as a result of a deliberate poisoning.
The scientists who tested samples of Arafat's remains for alleged poisoning said on November 7 they could neither confirm nor rule out polonium was the cause of his death, but that the amount they found could not occur naturally.
Allegations that Arafat had been poisoned surfaced immediately after his death in a French military hospital in 2004.
Arafat's widow Suha said on November 6 the Swiss report, which she had already received, suggested he had been assassinated.
Israel has repeatedly denied allegations by Palestinian officials it was involved in Arafat's death.
A top aide to former Israeli Prime Minister Ariel Sharon said Sharon had ordered that no harm was to be done to Arafat.
