A Palestinian investigator says Israel is the "only suspect" in the death of Yasser Arafat.
The investigator, Tawfik Tirawi, says Arafat did not die a natural death. However, he was evasive when asked whether Arafat was poisoned.
Speaking to reporters in Ramallah on today, a day after Swiss scientists who examined Arafat's remains said they found elevated levels of the radioactive substance polonium. They said their findings "reasonably" supported the theory that Arafat was poisoned.
Tirawi would only blame Israel for the Palestinian leader's death, saying that "Israel is the first, fundamental and only suspect in the assassination of Yasser Arafat."
Tirawi is the head of the Palestinian committee that is investigating Arafat's mysterious 2004 death. Israel has denied any role in the death.
