Peru's government has suspended civil liberties in a southern coastal valley after a fourth death in violent anti-mining protests against a Mexican-owned copper mining project.

Cabinet chief Pedro Cateriano announced the 60-day state of emergency Friday night. Troops will take to the streets in support of more than 2,000 police in the Tambo valley.

Cateriano said suspended rights would include assembly, freedom of movement and protection against searches without a warrant.

One protester was killed and four injured Friday in clashes, which have escalated since farmers mounted resistance two months ago to the $1.4 million project owned by Southern Copper.

Local medical director Walter Vera said a 55-year-old man was killed in Friday's violence.

Sixty-two percent of Peru's export revenues come from mining. It is the world's No. 3 copper producer.
