French prosecutors have opened a murder inquiry into the 2004 death of Palestinian Authority leader Yasir Arafat.
Suha Arafat, his widow, lodged a legal complaint for murder last month, and the French public prosecutor has now ruled that an inquiry can take place.
Mr Arafat, who died aged 75 in a military hospital in France, was said by French doctors to have died of a massive stroke.
However, an investigation by Al-Jazeera television channel, in which a Swiss institute examined a bag of Mr Arafat’s belongings, found that his items had elevated levels of lethal radioactive substance polonium-210.
The institute said that the findings were inconclusive, and that Mr Arafat’s bones needed to be tested.
The Palestinian authority has said that an exhumation of the body — he is buried in Ramallah — can go ahead, but no date has yet been set.
