The wife of a British journalist has said "now we can bring them home and say goodbye with love" after the bodies of her husband Dom Phillips and indigenous expert Bruno Pereira were found in the Amazon.

Brazil's justice minister Anderson Torres said the remains were found near where the pair disappeared on 5 June, with police saying a suspect led investigators to the location after confessing to the fatal shooting.

In a statement, Mr Phillips' wife Alessandra Sampaio said: "Although we are still awaiting definitive confirmations, this tragic outcome puts an end to the anguish of not knowing Dom and Bruno's whereabouts.

"Now we can bring them home and say goodbye with love.

"Today, we also begin our quest for justice. I hope that the investigations exhaust all possibilities and bring definitive answers on all relevant details as soon as possible."

It comes after former British prime minister Theresa May insisted the UK must do "everything it can" to press Brazilian authorities to uncover the truth about the disappearance.

Mrs May made the plea yesterday to Boris Johnson in the House of Commons after police arrested a second suspect in connection with the case.

The apparent killings of the two men were "monstrous" but should inspire the media to follow up their in-depth work on environmental crimes, a colleague said today.

Dom Phillips and Bruno Pereira went missing in a remote part of the Amazon that is rife with illegal mining, fishing and logging, as well as drug trafficking.

One of two men arrested over their disappearance has confessed to burying the pair in the jungle, Brazilian police said, after human remains were found.

"This is a horror story that will chill anyone who is a journalist, anyone who cares about the Amazon, about indigenous people, about our planetary life support systems," The Guardian's global environment editor Jonathan Watts, who is based partly in Brazil, told AFP.

"But I hope it will inspire rather than deter editors and reporters, so that there is even more attention on the stories that Dom cared about," he said.

"I really hope that the work Dom started can be continued and amplified. And that for me would be the only way something decent could come out of something so utterly monstrous."

Mr Phillips, 57, a long-time contributor to The Guardian and other leading international newspapers, was working on a book on sustainable development in the Amazon.

The highly regarded Mr Pereira, 41, was acting as his guide while on leave from his job at the Brazilian government's indigenous affairs agency.

The father of three had repeatedly reported being threatened by loggers, miners and illegal fishermen.

Pat Venditti, executive director of Greenpeace UK, praised Phillips and Pereira as "brave, passionate and determined men".

In a statement, he said they "were murdered while doing their vital work of shining a light on the daily threats Indigenous Peoples in Brazil face as they defend their land and their rights".

Mr Venditti accused Brazil's far-right president, Jair Bolsonaro, of giving "political and moral licence for predatory activities in and around Indigenous lands".

"The greatest tribute we can pay Bruno and Dom now is to continue their vital work until all of Brazil's peoples and their forests are fully protected," the Greenpeace official added.

One of two men arrested over the disappearance, Amarildo da Costa de Oliveira, confessed to having buried the pair in the jungle, federal police said.

They did not specify whether he also confessed to killing the paper.

The other suspect, a man reported to be Mr Oliveira's brother, Oseney da Costa Oliveira, was arrested on Tuesday in Atalaia do Norte

Police are also investigating the possible role of a third person.

Amarildo, a fisherman, was arrested on 7 June. Both he and Oseney are said to be in their early 40s.
