The Yasser Arafat Foundation said Sunday there was \"no need\" for more proof the Palestinian leader was poisoned in what appeared to be taking a stance against exhuming his body. \"Since the formation of this Foundation, it has forcefully held on to the fact that Yasser Arafat died abnormally after being killed by a poison which was unidentified at the time,\" a statement said. \"The Foundation does not see a need here for more proof,\" it said.
