British medical journal The Lancet has published a study by Swiss experts which suggests that there is a strong possibility that the late Palestinian President Yasser Arafat was poisoned by radioactive element polonium 210. The same conclusion was reached by an investigation conducted by Al-Jazeera TV that was broadcast in 2012.
The Swiss scientists at Lausanne University discovered high levels of the element in blood, urine, and saliva samples found on Arafat's clothes and toothbrush.
His belongings were handed over by Arafat's widow, Suha, to a military hospital near Paris. The initial research for Al-Jazeera was conducted by experts from Switzerland's Institut de Radiophysique.
