USA: Sioux tribe fights to protect its ancestral land

This week, we head to the US state of North Dakota, where the Sioux tribe is trying to stop a huge oil pipeline - they claim it will desecrate sacred land. We also go to Mexico to meet young people who have fled gang violence at home in Central America. Finally, we take a look at some of the main attractions at the Paralympics as they get under way in Rio.
