Portugal has declared three days of mourning for the 62 victims of one of the country's deadliest forest fires.
Four children are among the victims, many of whom were found dead inside their cars as they tried to flee the central forested region of Pedrógão Grande.
Hundreds of firefighters are continuing to tackle the blaze on several fronts.
Prime Minister Antonio Costa called it "the greatest tragedy we have seen in recent years in terms of forest fires".
He said it was thought to have been sparked by a lightning strike.
Four firefighters are among the 54 people injured in the fire, which is raging in several parts of a mountainous area some 200km north-east of the capital Lisbon.
There are fears the death toll could rise, as a number of people are still missing. The period of national mourning ends on Tuesday.
Bodies found inside cars
Emergency service workers were battling 156 fires across the country on Sunday, Prime Minister Costa said, adding that most of the victims had died in just one of them.
Secretary of State for the Interior Jorge Gomes said that most had died from smoke inhalation and burns, while two were killed in a road accident related to the fires.
Thirty bodies were found inside cars, with another 17 next to the vehicles, on one road leading on to the IC8 motorway.
Another 11 died in a village next to the motorway.
More than 1,600 firefighters are fighting five of the main fires, supported by about 400 vehicles and 18 aircraft, Portugal's Público reports.
According to the prime minister, just 11 fires are still active but he said the authorities were "particularly worried about two of them".
They have sent two army battalions to help the emergency services.
'I could have died, I should have died' - fire survivor's tale
As the power went off, the flames hit hard, a fiery red tornado passed the windows. We crouched on the floor for a good hour, trying to breathe, praying, crying.
I am not ashamed to say it: I was praying, we were all praying. I am not religious, but at that time, you couldn't do anything else.
I said: "It can't end like this." I just started crying and got emotional - I was no use to anyone for 20 minutes.
Eventually the fire passed and we emerged to see the smouldering remains of the village. Miraculously, our house and the one next door did not burn.
The devastation was indescribable. People, bewildered, remains of homes burning uncontrollably, concrete posts exploding over roads.
I couldn't believe what I was seeing. After the fire passed, it should still have been bright, but it was dark. There was a strange film over everyone's eyes.
You could hear gas canisters exploding, see blue flashes going off. There was just a strange silence. There was a lull, a strange feeling. It then turned to relief, there was crying.
France has offered three firefighting planes, while Spain has already sent two water-bombing aircraft to help tackle the fires. The European Union has also promised to provide firefighting aircraft.
Dozens of people who fled their homes have been taken in by residents of the nearby municipality of Ansiao.
Pope Francis, who visited Portugal last month, mentioned the victims in his weekly address: "I express my closeness to the beloved people of Portugal following the devastating fire."
French President Emmanuel Macron tweeted: "Solidarity with Portugal, hit by terrible fires. Our thoughts are with victims. France makes its aid available to Portugal."
The fires began on Saturday during an intense heatwave and rainless thunderstorms, with temperatures of more than 40C (104F) in some areas. Police say lightning striking a tree may have caused the fire.
"This is a region that has had fires because of its forests, but we cannot remember a tragedy of these proportions," Valdemar Alves, the mayor of Pedrógão Grande, was quoted as saying by the Associated Press agency.
"I am completely stunned by the number of deaths."
