Following a 34-month long lasting siege on his presidential headquarters in Ramallah and an associated restriction on his movement, Yasser Arafat unexpectedly died on 11th November 2004. The official statement announcing his death failed to determine a cause, saying only that he had a “mystery blood disorder”. The Palestinians accused Israel of poisoning Arafat with polonium-210. But, despite an exhumation of Arafat’s remains in 2012, independent investigations by a French, a Swiss and a Russian team of scientists came to different conclusions on the poisoning.
