The remains of former Palestinian leader Yasser Arafat will be exhumed Tuesday as part of a renewed investigation into his death. Arafat died in November 2004 in a French military hospital, a month after suddenly falling ill. Palestinian officials claim he was poisoned by Israel, but have not presented evidence. Israel has denied such allegations. Earlier this year, the detection of a lethal radioactive substance in biological traces on Arafat's clothing sparked a new investigation. Tests were inconclusive, and experts said they need to check his remains to learn more. On Tuesday, Swiss, French and Russian experts will take samples from Arafat's bones, said Tawfik Tirawi, who heads the Palestinian team investigating the death. They will examine the samples in their home countries.
