Reuters reported that 2 workers died and several disappeared during an attack on Chinese miner Zijin's highly controversial Rio Blanco copper project in northern Peru.

Mr Jian Wu, director of Zijin's Peru pertain told that about 15 to 20 armed people invaded the mining camp on Sunday and fired at its security guards.

As per report, the attack may have been an act of revenge. In 2005, one protester was killed and two dozen were tortured when townspeople mobilized to stop construction of the mine, which they said would cause pollution and hurt water supplies.

The mining development is run by Monterrico Metals of Britain, which was bought by Zijin Mining Group.
