Striking miners clash with riot police in Chile.
Officers use tear gas and water cannon to beat back the protesters at the state-owned Chuquicamata copper mine.
The contract workers are demanding wage increases and bonuses.
The copper industry here is booming and they say mining companies are keeping profits for themselves.
Chile, the world's largest copper producer, has been wracked by several similar strikes in recent years.
