Spike in wildfires in Brazil's Amazon rainforest - BBC News
Smoke from the fires caused a blackout in Sao Paulo, more than 2,700km (1,700 miles) away.
Brazil's Amazon rainforest is facing a record number of fires this year, according to new data from the country's space research agency.

The National Institute for Space Research said there had been an 83% increase on the same period in 2018.

Smoke from the fires caused a blackout in the city of Sao Paulo on Monday, more than 2,700km (1,700 miles) away.

But some meteorologists say the smoke came from major fires burning in Paraguay, which is much closer to the city and not in the Amazon region.
