The Peruvian government has imposed a night-time curfew in Pataz province, where 13 kidnapped mine workers were killed last week. President Dina Boluarte also ordered that mining activities be suspended for a month while extra police and soldiers are deployed to the region.

The men were killed in a region that has seen growing conflict over access to ore in recent years. The mine has also been a hotbed of illegal gold mining.

Much of Peru is awash in a wave of crime that prompted the government to declare a state of emergency last month​.
