BBC News. A catastrophic forest fire in Portugal has claimed at least 43 lives, officials say.
Many died while trying to flee the Pedrógão Grande area, 50 km (30 miles) south-east of Coimbra, in their cars, according to the government.
Several firefighters are among the 59 people injured.
“Unfortunately this seems to be the greatest tragedy we have seen in recent years in terms of forest fires,” said Prime Minister Antonio Costa.
The death toll could rise further, he said.
Secretary of State for the Interior Jorge Gomes said that three people died from smoke inhalation and 18 people travelling in four cars died on the road linking Figueiró dos Vinhos to Castanheira de Pera.
Media in Portugal said the fire is no closer to being contained despite about 600 firefighters working to put them out.
Among the 59 injured was an eight-year-old girl with burns found wandering alone close to the fire, the Correio do Manhã newspaper reported.
Six firefighters are seriously wounded, national broadcaster RTP said, and two are reported missing.
The Correio do Manhã warned that many areas hit by the fire had not yet been reached by authorities, so the death toll was likely to increase.
About 60 forest fires broke out across the country overnight, with close to 1,700 firefighters battling them across Portugal.
The flames spread “with great violence” on four fronts near Pedrógão Grande, Mr Gomes said.
Spain has sent two water-bombing planes to help tackle the fires.
It is not yet known what caused the fire, however Mr Costa said thunderstorms could have been one possible cause.
Portugal has been experiencing a heatwave, with temperatures of more than 40C (104F) in some areas.
“This is a region that has had fires because of its forests, but we cannot remember a tragedy of these proportions,” said 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.”
What happens next? Alison Roberts, BBC News, Lisbon
We have had large-scale fires before over the past couple of decades – this year is not unusual in that respect – but it is certainly unusual to have so many fatalities in one place.
There were very particular circumstances with the lightning strikes here – this fire started with a dry lightning strike. There has been rainfall elsewhere but there was no rain there, and this is a heavily-forested area.
Getting it under control depends not only on temperatures, which do seem as though they will be high, but on the wind above all. It is very much in the hands of Mother Nature.
