Several people have been injured during recent fighting between mine workers and union members at the Cananea copper mine in Sonora, Mexico, according to local media reports.

El Imparcial newspaper reported yesterday that a total of ten people were injured and 26 people were arrested on earlier this week. Three of the injured were shot.

The city government stated that one contract worker had died of bullet wounds, but later retracted the report of the death, according to Reuters.

Cananea, the largest copper mine in Mexico, has the capacity to produce 180,000 metric tons of copper annually, but has not been producing since the labour unrest began in 2007.
