The forensic examination of the Palestinian leader’s remains were released by his widow Suha on Tuesday, and immediately reported by al-Jazeera — the Arab satellite network that last year broke the news that Arafat’s clothes and personal effects contained suspicious traces of polonium 210, the radioactive isotope that killed Kremlin critic Alexander Litvinenko in London in 2006.

Swiss scientists exhumed Arafat’s body last November and tested his skeleton and grave for telltale evidence of the isotope. The verdict, a full year later: “The results moderately support the proposition that the death was the consequence of poisoning with polonium 210.”

Such a moderate word, moderately. It isn’t strongly, and certainly not conclusively. Details of the forensic examination might well encourage belief in the poisoning theory, laid out in table form — pro and con — on page 67 of the 108-page report, and clearly accumulating on the pro side. But every page of the PDF posted online carries the watermark of al-Jazeera, a marketing move of dubious value for a news organization that provokes such strong reactions all by itself, and is heavily invested in the story.
