Brazilian police have found possible human remains in their search for UK journalist Dom Phillips and indigenous expert Bruno Pereira.
The police say experts will analyse the “organic material” found in a river near the town of Atalaia do Norte in the remote Amazon rainforest.
The pair went missing while travelling by boat on a reporting trip on Sunday last week.
Blood traces found on a boat belonging to a fisherman, who has been arrested, will also be tested.
Indigenous groups say both men had received threats for their work in the region, which has seen illegal fishing, logging, mining and drug trafficking.
Both Mr Pereira, 41, and Mr Phillips, 57, who has written for publications such as the Guardian and the Washington Post, are hugely experienced and planned their journeys thoroughly. They reportedly had a new boat and plenty of fuel. END.
