In this major investigation, Al Jazeera reveals new evidence suggesting Palestinian leader Yasser Arafat was poisoned.

This documentary centres on scientific analysis of Arafat’s personal effects, which he wore and kept close to him in his final days.

Scientists from the University of Lausanne in Switzerland discover elevated levels of polonium on Arafat’s effects.

Polonium is a radioactive element that can be used as a poison.

This project also releases, for the first time, Yasser Arafat’s full medical records.

It includes a one-hour film, interactive features and exclusive documents and articles.
