(CNN) Brazil's President blamed an unusual candidate this week as a cause of the Amazon forest fires: actor and environmentalist Leonardo DiCaprio.

President Jair Bolsonaro made the claim Thursday on a webcast , arguing that nongovernmental organizations (NGOs) contributed to the forest fires that ravaged the Amazon rainforest earlier this year.

"The NGO people, what did they do? What's easier? Set fire to the bush," he said, providing no evidence to support the accusation.

He continued, "Take photo, film, send it to an NGO, the NGO spreads it out, does a campaign against Brazil, gets in touch with Leonardo DiCaprio and Leonardo DiCaprio donates $500,000 to this NGO. One part went to the people who were setting the fire, right?

"Leonardo DiCaprio, you are assisting with the burning of the Amazon, that can't be," Bolsonaro said.
