Suha Arafat, widow of late Palestinian Authority Chairman Yasser Arafat, has called to exhume his body following reports that he was poisoned. Al-Jazeera reported Tuesday that a Swiss institute found that Arafat may have died of polonium poisoning.

The institute reportedly examined bodily fluids found on Arafat’s personal belongings. If Arafat’s bones were examined and found to contain polonium as well, it would give substantial support to the poisoning theory.
