LISBON: Forest fires halted traffic on motorways in the Aveiro region of northern Portugal Monday as homes were engulfed by a string of blazes that broke out over the weekend, local authorities said.
Nearly 1,600 firefighters were battling 20 fires Monday, with the country placed on alert from Saturday to Tuesday evening because of high temperatures and strong winds.
More than 500 have been battling the largest fire near Oliveira de Azemeis, south of the city of Porto, since Sunday.
Further to the south, at least two homes were burned in two villages in the Albergaria-a-Velha area, said mayor Antonio Loureiro.
“We already have houses in flames at the moment,” he told Portuguese news agency Lusa.
Traffic has been halted on three motorways in the area, police said.
Drivers were told not to try to get to Aveiro. “That is the best way to not to put lives at risk,” said mayor Vitor Ribero.
One firefighter died “suddenly” Sunday while taking a break from efforts to contain the fire, the interior ministry said Monday.
Portugal has seen less wildfires than usual so far this year. Some 10,300 hectares (25,500 acres) were lost to the flames by the end of August — a third of what was destroyed last year and seven times less than the average over the last decade.
Lisbon has upped fire prevention funding ten-fold and doubled the budget to fight wildfires since deadly blazes in 2017 claimed hundreds of lives.
Scientists say human-caused fossil fuel emissions are increasing the length, frequency and intensity of global heatwaves, raising the risk of wildfires.
The Iberian peninsula is particularly vulnerable to global warming, with heatwaves and drought exposing the region to blazes.

MAIDUGURI: People in Nigeria’s flood-hit northeastern Borno state are struggling to get medical care as overwhelmed aid agencies warn of an outbreak of waterborne disease following the worst floods to hit the region in three decades.

More than 30 people have been killed by the floods, which authorities say affected about one million people, most of whom are housed in camps without food and clean water.
The deluge threatens not only the health and safety of the displaced but puts a strain on aid agencies and government resources, exacerbating an already critical humanitarian crisis.
The floods in Borno, the birthplace of Boko Haram militants in the Lake Chad basin, started when a dam burst its walls following heavy rainfall that has also caused floods in Cameroon, Chad, Mali and Niger, all part of Africa’s Sahel region that usually receives little rain.
In the last two weeks of August, more than 1.5 million people were displaced across 12 countries in West and Central Africa due to floods, and about 465 have been killed, according to the United Nations humanitarian affairs office.
Over the weekend, an additional 50,000 people were displaced in northeastern Nigeria as the floods intensified, the Norwegian Refugee Council (NRC) said on Monday.
“The situation in the Sahel and Lake Chad region is increasingly dire, as the compounding effects of conflict, displacement and climate change take a severe toll on vulnerable populations,” said Hassane Hamadou, NRC’s Central and West Africa regional director. The floods in West Africa come at a time of flooding in Europe after days of torrential rain that caused rivers to burst their banks in several parts of the region.
In a camp in Maiduguri, Borno’s state capital, Bintu Amadu was among hundreds of frustrated people waiting for hours to see a doctor because her son had diarrhea.
“We have not received any aid, and our attempts to see a doctor have been unsuccessful. We have been waiting for medical attention since yesterday, but to no avail,” she said.
Ramatu Yajubu was happy she had obtained an appointment card after waiting for days, but quickly added: “I am uncertain about receiving attention due to the overwhelming number of people seeking care.”
Mathias Goemaere, a field coordinator for Medecins Sans Frontieres, said that even before the floods, residents in Borno were struggling with malnutrition, following years of an Islamist insurgency that has driven people from their farms.
“They are exposed to their environment, so what do we see? A lot of waterborne diseases, diarrhea, diarrheal diseases ... Malaria is around with a lot of mosquitoes,” Goemaere told Reuters.
“So a lot of people, because of malnutrition, are immuno-suppressed, which makes them more susceptible to diseases.”
Nigeria’s government has separately warned of rising water levels in the country’s largest rivers, the Benue and Niger, which could cause floods in the oil-producing Niger Delta region in the south.
