A British couple have been found down a ravine, badly burned and semi-conscious, after being caught up in the deadly wildfires that tore through Spain’s Almeria province, according to local media.

The pair are thought to have been out hiking when they were caught up in the blaze, which spread rapidly through the province on Thursday. They were evacuated and taken to hospital where they are in intensive care.

Hundreds of firefighters have been battling the fires, which have claimed the lives of 12 people including 4 Britons, and burned through 6,600 hectares (16,300 acres).

The identities of those killed have not yet been officially confirmed.

The couple were discovered by Civil Guard officers searching for survivors near the worst-hit village of Bedar in the early hours of Friday morning.

One of the rescuers, Sergeant Pedro Barre, said they heard distant cries for help.

“As you gain more experience, something inside you tells you, ‘Look again, try one more time,'” he told Spain’s TVE state broadcaster.

The rescue team followed the sound and climbed down a hillside. They found the couple in critical condition, semi-conscious and with severe burns covering 40% of their bodies.

“Being able to call out in the condition they were in was a titanic effort,” said Rafael Zea, another of the officers involved in the operation.

“We’ll never forget that look of surprise and emotion on their faces,” Barre added.

On Saturday the authorities said firefighters had made significant progress in getting the fires under control.

Calmer winds and higher air humidity were expected to help the firefighters tackle the blaze.

About 600 of the nearly 1,500 people evacuated from the fire zone in Almería province were told they could return, regional emergency chief Antonio Sanz said.

A sustained heatwave with temperatures of around 40C (104F) has caused wildfires across Southern Europe this summer, particularly in France, Portugal and Spain.

On Friday, Los Gallardos mayor Francisco Miguel Reyes told Spanish radio station Cadena SER said “it feels like a bomb has fallen” on the area.

“This is the first time we’ve faced a fire as devastating as this.”

Hundreds of firefighters, military and law enforcement personnel, and 30 aircraft, continued responding to the blaze.

Forensic scientists in Madrid are using samples from the bodies of the victims and DNA samples from the families of those reported missing to try to identify the dead.

The identification process has been slowed because collecting DNA samples from relatives has proved difficult, with family members traveling from other countries.

With at least 12 people dead, this is already among the deadliest wildfires in Spanish history.

In 1984, 20 people died in a fire on the Canary Island of La Gomera, while in 1979, 21 people, including nine children, died in a forest fire near Lloret de Mar in north-eastern Spain.

Wildfires have also plagued France over the summer months.

On Monday over 10,000 people were evacuated from their homes in the foothills of the French Pyrenees.

French authorities said on Saturday 32 people had been arrested on suspicion of starting the fires.

Climate change is driving up temperatures around the world, and Europe is the fastest warming continent, heating up twice as fast as the global average, according to the Copernicus climate service.

This is causing increased summer heatwaves, greater pressure on Europe’s water supply, and more intense wildfires.
