RIO DE JANEIRO (AP) - Brazil's President Jair Bolsonaro on Tuesday (Dec 10) called young Swedish environmental activist Greta Thunberg a "brat" after she expressed concern about the slaying of indigenous Brazilians in the Amazon.
Bolsonaro questioned the coverage news media have given Thunberg, 16, who who on Sunday tweeted a link to a story about the murder of two indigenous people in Brazil's Maranhao state.
"Greta said that the Indians died because they were defending the Amazon," Bolsonaro told a group of journalists.
"It's impressive that the press is giving space to a brat like that," he added, using the Portuguese word word "pirralha".
Following Bolsonaro's comments, Thunberg changed the bio on her Twitter profile to say "Pirralha".
Thunberg became a symbol for youth demanding radical change to confront climate change when she sparked global school strikes.
Her comments about the deaths of the indigenous people came as the UN was hosting its international climate change conference, where Brazil's environmental policies have been the subject of criticism.
Deforestation of its Amazon rose nearly 30 per cent in the 12 months through July.
"Indigenous people are being literally murdered for trying to protect the forrest (sic) from illegal deforestation," she tweeted.
"Over and over again. It is shameful that the world remains silent about this."
The remark by Bolsonaro -and Thunberg's reaction- caught the attention of Brazilian environmental activists at the COP25 climate talks in Madrid.
Gabriela Baesse, 27, said that the exchange showed the Brazilian president "doesn't understand the youth."
Marina Silva, a centre-left politician and former environment minister under Luiz Inacio Lula da Silva's administration, said Bolsonaro's move was "incoherent" with his leadership position.
"He should not worry about fighting Greta because she showed solidarity with the indigenous that were murdered," Silva said.
"He should fight the criminals that murdered the indigenous instead of fighting Greta."
The comment by Bolsonaro, who has frequently expressed his admiration for his US counterpart, follows Donald Trump's sarcastic dig at Thunberg in September.
Trump responded to a video of Thunberg discussing suffering people, dying ecosystems and looming mass extinction, saying, "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!"
