reported that the Swiss forensic team had found levels of polonium in Arafat's ribs and pelvis 18 times higher than normal, and were 83% confident that polonium poisoning had occurred, but Professor Bochud disagreed with this interpretation by Al Jazeera and only stated that the poisoning hypothesis by polonium was "moderately supported". According to a journalist from the Swiss daily newspaper Le Temps, Luis Lema, the Swiss experts had concluded that on a probability scale ranging from one to six, death by polonium poisoning was around five. Arafat's widow Suha stated her belief that he was a victim of a "political assassination" but refrained from finger-pointing and said she would await the French forensic results. Joods Actueel, a Belgian monthly newspaper, claimed that most experts in forensics disagreed that the results were consistent with polonium poisoning and that the conclusions of the Swiss study were not in line with the results obtained. Forensic biologist Nathan Lents of the John Jay College of Criminal Justice said the report's results were consistent with a possible polonium poisoning, but "There's certainly not a smoking gun here." Derek Hill, a professor in radiological science at University College London who was not involved in the investigation, said: "I would say it's clearly not overwhelming proof, and there is a risk of contamination (of the samples), but it is a pretty strong signal. ... It seems likely what they're doing is putting a very cautious interpretation of strong data." After the testing of Arafat's remains by the Russian team, the Russian Medical-Biological Agency concluded that polonium was not the cause of his death. However, the government scientific body later denied that it had made any official statement about the research, saying only that it had handed its results to the Russian Foreign Ministry. However, Al Jazeera found that the Russian scientists had only investigated four out of 20 samples, being the samples that were unlikely to show the amount of radioactive exposure. The scientists also appear to have been restricted by the Russian Foreign Ministry in how to present the report. According to Al Jazeera's source, "Russia's goal was to fulfill the Palestinian Authority's request, not offend Israel by helping the PA, and not create a new hotbed in the Middle East". In December 2013, an unidentified person leaked what were claimed to be the results of the French investigation to AFP, saying that "the report
