Dom Phillips, a Guardian contributor, was last seen on Sunday morning travelling with Indigenous expert Bruno Araújo Pereira
The US climate envoy John Kerry has committed to pursuing the facts behind the disappearance of a veteran Guardian contributor and a celebrated Indigenous expert in the Brazilian Amazon.
Dom Phillips and Bruno Araújo Pereira were last seen on Sunday morning travelling by boat through the remote Javari Valley, a region plagued by violence involving illegal fishermen, illegal loggers, drug traffickers and security forces.
Kerry, a former US secretary of state, appears shocked at details of the case recounted by the Brazilian Indigenous leader Sonia Guajajara in a WhatsApp video of the encounter seen by the Guardian.
