Investigators are expected to exhume the remains of the late Palestinian leader Yasser Arafat today in an attempt to determine how he died. Swiss, French and Russian experts will take samples to establish whether his death, at a military hospital in Paris in 2004, was the result of poisoning. France began a murder inquiry in August after Swiss experts found radioactive polonium-210 on his personal effects. Arafat's medical records say, he had a stroke resulting from a blood disorder. His widow, Suha, objected to a post-mortem at the time, but asked the Palestinian Authority to permit the exhumation to reveal the truth. The head of the Palestinian Committee investigating Arafat's death, Tawfik al-Tirawi has said that no journalists will be allowed to observe the exhumation.
