Peru president urges calm in Cajamarca mine protest

Peru's President Ollanta Humala has imposed a state of emergency in the northern region of Cajamarca, which has seen bitter protests against a gold mining project.

Mr Humala said the measure in four towns would last for 60 days, and was aimed at restoring calm to the troubled area.

Protesters say the project will destroy local water supplies, but Newmont Mining Corporation says its plans meet the highest environmental standards.
