The death of the late Palestinian leader Yasser Arafat is now the subject of a murder investigation.
 
It follows an Al Jazeera documentary which revealed high levels of Polonium-210 on his clothing, the same radioactive element that killed former Russian spy, Alexander Litvinenko.
 
Arafat died in a military hospital near Paris in 2004, aged 75.
 
French prosecutors opened the investigation after a complaint lodged by Arafat's widow Suha.
