Brazilian President Jair Bolsonaro has ordered army units to help fight the Amazon wildfires more than a week ago, blaming the weather after international pressure on Brazil as the "lung of the world."
Bolsonaro criticized the reactions of European countries and said there were forest fires all over the world, but the fires could not be used as a pretext for sanctions.
In a televised speech, he said the government was well aware of the situation and would fight "environmental crime" in the same way as ordinary crime.
On Twitter, Bolsonaro accused his French counterpart Emmanuel Macron of wanting to "incite hatred against Brazil." "The strongest fire is the one that strikes our sovereignty on the Amazon," he wrote before.
Mr Macron has accused Bolsonaro of "lying" about his environmental pledges, and said he could hinder efforts to ratify the trade agreement between the European Union and the South American Common Market (Mercosur).
For his part, British Prime Minister Boris Johnson that the fires constitute an "international crisis" before the summit of the Group of Seven, which is held today and tomorrow and expected to come out "concrete initiatives" in this regard.
US President Donald Trump offered Bolsonaro US help.
Environmental groups have staged protests in various Brazilian cities to demand fire-fighting measures.
Demonstrations were also held in several countries in front of the Brazilian embassies in protest against the Amazon fires and criticism of the fire-fighting failure in the so-called "Lung of the World", home to about 3 million plant and animal species and 1 million indigenous people.
The Brazilian National Institute has previously reported about 2,500 fires in the past two days alone, as huge fires threaten the Amazon's forests and their role in the global ecological balance.
Since the beginning of this year, these forests have been exposed to more than 75 thousand fires, a record increase of 84% over the fires that broke out in these forests last year.
