Amazon fires

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.
