Arafat, a Nobel Peace Prize winner who led the struggle for Palestinian statehood for nearly four decades, died on November 11, 2004, following several weeks of treatment.
He had been airlifted to France from his besieged headquarters in the Israeli-occupied West Bank.
French officials, citing privacy laws, refused to reveal the precise cause of death or the nature of his condition, fuelling a host of rumours and theories as to the cause of his illness.
At the time of his death at the age of 75, Palestinian officials charged he had been poisoned by longtime foe Israel, but an inconclusive Palestinian investigation in 2005 ruled out cancer, AIDS or poisoning.
To confirm the theory that he was poisoned by polonium it would be necessary to exhume and analyse Arafat’s remains, Bochud said.
“If (Suha Arafat) really wants to know what happened to her husband (we need) to find a sample — I mean, an exhumation... should provide us with a sample that should have a very high quantity of polonium if he was poisoned,” he said.
