At least two more people were shot and injured during the attacks on the Tucari mine.

The mine was raided by at least 12 people, who also kidnapped the superintendent and head of security.

Workers say the robbers stole around 30 bars of dore, a gold and silver mix worth an estimated $1.2 million.

This attack is potentially very damaging for Peru which is one of the world's biggest gold producers.

Until now, co-ordinated attacks such as this have been virtually unheard of and experts fear this could affect foreign investment in Peru and in turn the country's economy, which relies so heavily on the rising price of gold.
