MADRID — One of Spain’s deadliest wildfires on record killed 12 people overnight into Friday, authorities said, as soaring temperatures grip much of the country.

Several victims of the fire in the southern province of Almeria, a popular holiday destination, were found inside burnt-out vehicles and were thought to have died while trying to flee the flames.

Eight people have been injured and a further 23 are unaccounted for, Andalusia’s regional leader Juan Manuel Moreno said. Some 150 firefighters and 220 soldiers from Spain’s military emergency unit were battling the blaze, which has consumed more than 3,200 hectares (7,900 acres) of forest and farmland.

Regional emergency authorities said four British nationals and other unspecified foreign nationals appeared to be among the dead.

Victims attempted to flee on foot and by car

The fire broke out in a hamlet in a semi-arid area near the Sierra de Los Filabres mountains. Authorities have not confirmed the cause, but said people who called to report the fire said that a fallen power line had sparked a blaze that spread rapidly into a nearby forest.

Most of the victims died while attempting to flee and ignored shelter-in-place instructions, said Antonio Sanz, president of Andalusia’s emergency services. One group did so via a dry riverbed, which “turned into a death trap,” he said.

Seven people died while on foot after abandoning their cars, Sanz said, likely looking for a way out.

“The consequences have been terrible. Everything seems to indicate that, in the case of the deceased … we are dealing for the most part, if not entirely, with foreign nationals,” Sanz said.

Spanish Prime Minister Pedro Sánchez expressed his condolences. “Immense sadness and desolation in the face of the terrible consequences of the fire affecting the province of Almeria,” he wrote on X.

Europe battles intense heat again

Spain has battled frequent and severe heat waves in recent years, with temperatures often exceeding 40 C (104 F). Wind, high temperatures and little rainfall help small wildfires grow into unchecked blazes.
