Members of the Argentine Mapuche community have protested against a deal struck between Argentina's state-owned energy company YPF and the US firm Chevron to extract shale oil and gas from one on the largest deposits in the world.
They claim they were not consulted on plans to extract the resources from the site in southern Neuquen province - land which they claim as their own - nor were they informed of the potential environmental impact.
YPF has said the wells are on government-owned land and are being developed to the highest environmental standards
