Brazilian troops have been deployed in the Amazon to fight fires that have swept the region and prompted anti-government protests as well as an international outcry.
Some 44,000 troops will be available for “unprecedented” operations to put out the fires, and forces are heading to four Brazilian states that asked for federal help to contain the blazes, defence minister Fernando Azevedo said.
The Amazon fires have become a global issue, escalating tensions between Brazil and European countries who believe Mr Bolsonaro has neglected commitments to protect biodiversity.
Protesters gathered outside Brazilian diplomatic missions in European and Latin American cities Friday, and demonstrators also marched in Brazil.
The dispute spilled into the economic arena when French leader Emmanuel Macron threatened to block a European Union trade deal with Brazil and several other South American countries.
He wants G7 leaders meeting at a summit in France this weekend to discuss the Amazon crisis.
