In a report published by The Lancet, the team provide scientific details to media statements made in 2012 that they had found polonium on Arafat's belongings.
Arafat died in France on November 11 2004 at the age of 75, but doctors were unable to specify the cause of death. No autopsy was carried out at the time, in line with his widow's request.
His remains were exhumed in November 2012 and samples taken, partly to investigate whether he had been poisoned – a suspicion that grew after the assassination of Russian ex-spy and Kremlin critic Alexander Litvinenko in 2006.
That investigation is ongoing, conducted separately by teams in France, Switzerland and Russia. » | Edited by Harriet Alexander | Monday, October 14, 2013
