THE GUARDIAN WEEKLY: The latest issue features ‘Flollowing The Amazon Defenders’ – A journey to the heart of the rainforest, three years after the deaths of Dom Phillips and Bruno Pereira…

It’s three years since the murders of the journalist Dom Phillips and the Indigenous activist Bruno Pereira, who were both killed on a visit to the remote Javari valley in the Brazilian Amazon.

Dom was a Guardian contributor based in Brazil, whose reporting often appeared in the Guardian Weekly. Last week his widow, Alessandra Sampaio, came to visit our London offices along with Beto Marubo, an Indigenous leader from the Brazilian Amazon.

From the other side of the world it’s easy to feel far removed from the activities of criminal gangs that threaten the Amazon’s Indigenous people and plunder its natural resources. But hearing Beto and Alessandra speak so powerfully about the impact of Dom and Bruno’s work reminded me why we need to stay focused on a region that defies easy scrutiny.
