Secretary of State of Internal Administration Jorge Gomes had previously put the death toll at at least 43 people.
Jorge Gomes said that about 600 firefighters have been trying to put out the fires since Saturday.
He reported that at least 18 people were “burned to death in their cars,” while several others died from smoke inhalation.
Six firefighters have been injured, Gomes added.
Eighteen of the 59 injured are being treated in hospitals in Lisbon, Coimbra, and Porto, Gomes said, as cited by local media.

“This is a region that has had fires because of its forests, but we cannot remember a tragedy of these proportions,” said Valdemar Alves, mayor of Pedrogao Grande. “I am completely stunned by the number of deaths.”
The country’s prime minister has called it “the biggest tragedy of human life that we have known in years.”
The massive fire may have been caused by a lightning strike, as a damaged tree has been found, according to AP, citing police officials. The tree had been struck during a dry thunderstorm, which frequently spark wildfires. Such dry lightning storms occur in extremely hot dry conditions when rain evaporates before reaching the ground.

Since noon on Saturday when the fire started in a mountainous area of the central Leiria district, measuring some 128 square kilometers, it has spilled over to another three municipalities: Castanheira de Per in Leiria, Figueiro dos Vinhos, and Gois.
The blaze has been exacerbated by extremely high temperatures, which have gone as high as 40 degrees Celsius (104 degrees Fahrenheit).
“The fire continues with four active fronts, very violent, very strong, and reinforcements are continuing to arrive,” Gomes said on Saturday, while enacting an emergency civil protection plan in Leiria. He said that a field hospital and an additional mortuary have been set up as part of the effort.
Costa said the government’s main priority for now is “to save people who could still be in danger” and contain the fire.
