Dozens of people are estimated to have been killed in clashes between police and indigenous activists protesting oil and mining projects in the northern Peruvian Amazonian province of Bagua.

Peruvian authorities have declared a military curfew, and troops are patrolling towns in the Amazon jungle.

Authorities say up to twenty-two policemen have been killed, and two remain missing.

The indigenous community says at least forty people, including three children, were killed by the police this weekend.
