According to Russian forensic experts Yasser Arafat died of natural causes not radiation poisoning.

They are the latest to give an opinion on the former Palestinian leader’s death in 2004.

The Russian announcement is more strategic than scientific. It's obvious that one cannot ascertain after 8 years without reasonable doubt if Arafat was poisoned with polonium or not. Yet, Putin's government cannot afford any extra distraction before Sotchi Games. WHY? Because 85% of rogue Polonium sales are traceable to Russia and 15% to other former Russian Republics.
