Eight years after the death of Palestinian leader Yasser Arafat, Al-Jazeera network published on Tuesday findings of an investigation which attempts to shed light on the circumstances of his death. According to the report, Swiss experts found high levels of polonium, a highly radioactive element, in his personal belongings.

Arafat's death on November 11, 2004, had generated no small number of conspiracy theories, including poisoning by Israel and even HIV.

Al-Jazeera's report cites experts from the Institut de Radiophysique in Lausanne, Switzerland, who examined Arafat's belonging. "Tests reveal that Arafat’s final personal belongings – his clothes, his toothbrush, even his iconic kaffiyeh – contained abnormal levels of polonium, a rare, highly radioactive element," Al-Jazeera reported.

The tests that were conducted in Paris immediately after Arafat's death found no evidence of poisoning. Al-Jazeera's research indicated that Arafat was in good health until falling suddenly ill in October.

In 2005, Haaretz reported that Israeli experts who analyzed the report drawn up by the medical team that treated Yasser Arafat in Paris say that the most likely possibility is that he was poisoned in a dinner meal on October 12, 2004.
