Brazil's Amazon rainforest has seen a record number of fires this year, new space agency data suggests.
The National Institute for Space Research (Inpe) said its satellite data showed an 84% increase on the same period in 2018.
It comes weeks after President Jair Bolsonaro sacked the head of the agency amid rows over its deforestation data.
The largest rainforest in the world, the Amazon is a vital carbon store that slows down the pace of global warming.
It is also home to about three million species of plants and animals, and one million indigenous people.
Conservationists have blamed Mr Bolsonaro for the Amazon's plight, saying he has encouraged loggers and farmers to clear the land, and scientists say the rainforest has suffered losses at an accelerated rate since he took office in January.
Meanwhile, US space agency Nasa said that overall fire activity in the Amazon basin was slightly below average this year.
The agency said that while activity had increased in Amazonas and Rondonia, it had decreased in the states of Mato Grosso and Pará.
It was earlier reported that a blackout on Monday in the city of São Paulo - more than 2,700km (1,700 miles) away - had been caused by smoke from the Amazon fires.
But some metereologists say the smoke came from major fires burning in Paraguay, which is much closer to the city and not in the Amazon region.
