In Peru, the government has declared a “state of emergency” in the highland province of Espinar, saying two people were killed and dozens of police officers injured in anti-mining protests. Protesters have halted production at a copper mine owned by a Swiss-based company, Xstrata plc, saying the mine is contaminating local water supplies. The 30-day “state of emergency” places the military in charge and allows for the suspension of civil liberties.
