Israel denied it had any connection to the 2004 death of Palestinian leader Yasser Arafat's Thursday, the day after Al Jazeera published a report by Swiss scientists saying Arafat may have died of radiation poisoning.
"There is no Israeli connection to this in any way," said Israeli Foreign Ministry spokesman Yigal Palmor, responding to a question from dpa.
The report's conclusions "are totally inconclusive," he said.
"Therefore, what we have here is not a scientific proof determining the cause of death, but rather yet another episode in the endless soap opera in which Suha Arafat confronts the Palestinian Authority," he said, referring to Arafat's widow.
"This theory has more holes in it than Swiss cheese," he said.
The Al Jazeera report did not touch upon the issue of who might be behind any poisoning.
Members of the Palestinian Authority committee investigating Arafat's death said they would not comment on the matter until after a news conference, where the results of reports by French and Russian scientists would also be related.
The exact time or date of the news conference was not given, as the PA was waiting for an analysis by its own experts of the three reports.
The three teams from Switzerland, Russia and France took samples from Arafat's grave for testing of polonium-210 in November last year.
"Taking into account the analytical limitations aforementioned, mostly time lapse since death and the nature and quality of the specimens, the results moderately support the proposition that the death was the consequence of poisoning with polonium-210," reads the conclusion on page 69 of the 108-page report by the University Hospital Center in Lausanne.
The Russian experts said in mid-October they had found no evidence of polonium poisoning.
"He could not have died of polonium poisoning - the Russian experts found no traces of this substance," Vladimir Uiba, the head of Russia's Federal Medical-Biological Agency, told the Interfax news agency last month.
Palestinians have accused Israel of poisoning Arafat, who died at the age of 75 at a French military hospital outside Paris on November 11, 2004.
