The Israeli government has denied any role in the death of Yasser Arafat, saying that he was 75-years-old.
"This is more soap opera than science, it is the latest episode in the soap in which Suha opposes Arafat's successors," Israeli Foreign Ministry spokesman Yigal Palmor said.
The investigation amounted to "a highly superficial attempt to determine a cause of death".
