Al Jazeera has obtained the conclusion of the report by Russian scientists testing for polonium in Yasser Arafat's bones.

In it, the scientists measure only four of 20 samples and say their findings are inconclusive.

But a source has told Al Jazeera's Investigative Unit the scientists were given specific instructions by the Russian foreign minister.

This is a excerpt from the upcoming Al Jazeera documentary, Killing Arafat, which airs on Sunday, November 10, at 19:00 GMT.
