New Caledonia unrest explained

Police have used tear gas and stun grenades on rioters at an airport near Nouméa as the unrest and rioting in New Caledonia goes into its sixth day. Five people, including two police officers, have died and hundreds of people are injured amid clashes between authorities and pro-independence protesters. They were sparked by anger at a proposed new law that would allow French residents who have lived in New Caledonia for more than 10 years to vote - which some say will weaken the indigenous Kanak vote. Correspondent for Islands Business Magazine, Nic Maclennan, who has been covering this story for decades, explains the back-story.
