RAMALLAH - Late Palestinian leader Yasser Arafat's body will be exhumed on Tuesday to determine whether he was poisoned, investigative committee sources told Xinhua.

The investigation is aimed at verifying if Arafat's death at a French hospital near Paris in 2004 was due to poison. Last week, excavation started in Arafat's tomb in preparation for the exhumation of his remains.

The controversy over Arafat's death of an undiagnosed disease renewed when the pan-Arab Al-Jazeera news network aired a documentary in July saying that the Palestinian leader was poisoned with radioactive polonium-210. The Qatari television tested some of Arafat's personal belongings in a Swiss lab, which found significant traces of polonium on his toothbrush and underwear.
