Palestinians question Israel's role in Arafat's death

8 November 2013 Last updated at 14:05 GMT

The Palestinian authorities investigating the death of their former leader, Yasser Arafat, say scientific tests on his body show he did not die naturally.

The allegation follows a report published earlier this week by Swiss scientists, which found that Mr Arafat's exhumed body contained 18 times the normal level of the radioactive element, polonium.

Israel has dismissed any suggestion that it was involved.
