Reuters reported that Mexican miners clashed briefly with federal police at the Cananea copper mine raising tensions which could complicate owner Grupo Mexico's efforts to reopen the pit after a nearly 3 year long strike was broken.
The union said in a statement that 2 people were injured during the scuffle which began when unionized miners tried to block contract workers from entering the mine to start repairs.

Mr Manny Armenta a visiting representative of the United Steelworkers union said that there were three large buses of scabs was bringing into the property and there was a confrontation between the miners and the federal police. The US union has backed the miners.

Television images of the clash showed miners throwing rocks at police in riot gear and security forces responding by shooting tear gas guns at the workers on a road near the mine. Federal Police took control of the mine in a late Sunday night raid after the union lost a long series of legal battles and a court ruled Grupo Mexico could fire the workers and reopen the copper mine, Mexico's largest.
