A Swiss laboratory research has finally declared in its recent findings that the late Palestinian leader Mr. Yasser Arafat, who died in 2004, was poisoned with polonium.

Arafat, also a Nobel Peace Prize winner, played the major role in the struggle for Palestinian statehood. He led the fight on for almost four decades. His news of death came as a shock for many on November 11, 2004, after several weeks of treatment that was running to treat the poisonous effect.

Experts working in the case said that the above findings are based upon the analysis ran over the biological samples taken from the leader's belongings.

Mr. Arafat died at the military hospital in Paris and soon after his death; his body was handed over to his wife Suha to perform further rituals.

Mr. Francois Bochud, Head of the Institute of Radiation Physics at the University of Lausanne, Al-Jazeera said in his report today that the findings from the research have confirmed that Arafat was poisoned by polonium, which was also used to kill Russian former spy-turned-Kremlin critic Mr. Alexander Litvinenko, who died in the year 2006.

"The conclusion was that we did find some significant polonium that was present in these samples", Mr. Bochud told Al-Jazeera.
