Was Yasser Arafat murdered?

Al-Jazeera has apparently published a report showing Swiss scientists have found evidence the Palestinian leader was poisoned back in 2004.

The first forensic tests on remains from his exhumed corpse have reportedly shown unexpectedly high levels of radioactive polonium-210, suggesting the Palestinian leader could have been poisoned.

Arafat died in 2004 four weeks after he first fell ill shortly after eating dinner, and was almost certainly murdered by poisoning.
