The Palestinian Authority (PA) dug up the body of its late President Yasser Arafat on Tuesday as part of an international investigation into whether he was poisoned. The investigation was launched this summer, eight years after Arafat's death, when a Swiss lab found traces of the radioactive element polonium on Arafat's personal effects. The exhumation comes at a sensitive time, as the PA is suffering from a legitimacy crisis and is being upstaged by its rival Hamas. The exhumation also distracts attention from the the group's bid to upgrade its status at the U.N.
