The widow of late Palestinian Authority leader Yasser Arafat said on Wednesday that she was still convinced he was poisoned, after French experts ruled out the theory that he had been assassinated.    

"I'm still completely convinced that the martyr Arafat did not die a natural death, and I will keep trying to get to the truth," Suha Arafat told AFP.    

"I'm shocked by (the results of) the French medical report, which I only received four pages of to look at," she said.    

The French experts' findings, released Tuesday, differed significantly from those of Swiss scientists, who said last month their research offered some support for the suggestion Arafat was killed by polonium poisoning.    

"The Swiss report was a detailed, 107-page, professional report talking in detail about the presence of polonium on Arafat's clothes," Suha said.    

"How the French haven't found anything is completely illogical," she added.    

A source close to the French investigation said Tuesday it "rules out the poisoning theory and goes in the sense of a natural death".    

The circumstances of Arafat's death aged 75 at a military hospital near Paris in November 2004 after a sudden deterioration in his health have long been mired in rumor, speculation and conspiracy theories.    

French doctors were unable to say what killed him and an autopsy was never performed, at the request of his widow Suha.    

France opened a formal murder inquiry in August 2012, a month after an Al-Jazeera documentary linked Arafat's death to polonium poisoning.    

Some 60 samples were taken from Arafat's remains in November 2012 and divided between Swiss and Russian investigators and a French team carrying out a probe at his widow's request.    

Many Palestinians believed he was poisoned by Israel - a claim repeatedly denied by the Jewish state.    

Israeli foreign ministry spokesman Yigal Palmor told AFP the results of the French probe were "no surprise".
