Il Nuovo Postiglione - Spanish soldier dies in Aragon wildfire: regional leader

"I have conveyed my heartfelt condolences to the lieutenant general of the Military Emergencies Unit (UME) for the death of a soldier in the Penas de Riglos fire," Jorge Azcon said on X.

"All my love and support for his family, his colleagues and the whole UME at this time of deep pain," Azcon said.

Like its European neighbours, Spain has suffered several spells of extreme summer heat, contributing to ideal conditions for a string of wildfires.

Scientists say climate change, driven by humanity's burning of fossil fuels, is increasing the length, frequency and intensity of such extreme weather.

The regional government had announced the largest firefighting deployment in Aragon's history, including French reinforcements, to tame the blaze that broke out on Monday.

The flames have come close to the two monasteries of San Juan de la Pena, which are perched in mountainous, rugged terrain and are a symbol of the region.

The oldest monastery, linked by legend to the Holy Grail, has origins in the 10th century and contains the remains of the first kings of the medieval kingdom of Aragon, which were rescued on Thursday.

A complicated week marked by unpredictable winds and high temperatures saw the flames spread across 16,600 hectares (41,000 acres) and prompted the evacuation of more than 1,000 people from surrounding villages.

- 'Optimism and caution' -

The regional government reported "a night of positive work" on Sunday as firefighters "managed to consolidate a large part of the perimeter".

They would be reinforced with the arrival of 100 French firefighters and the participation of between 35 and 40 aircraft, it added in a statement.

Existing reinforcements from the army and other parts of Spain would take the total to 1,000 firefighters, which Azcon said was "the largest deployment of resources against a fire in Aragon's history".

"We're facing the day with optimism, but also with total caution," he wrote on X.

In the southern region of Andalusia, authorities allowed more than 400 evacuees to return home after a wildfire that has raged for 10 days and affected more than 25,000 hectares was declared under control on Sunday.

Andalusia's leader Juanma Moreno said it was "probable that the burned area is smaller than what we were estimating at the start", pending satellite analysis.

In late July, a wildfire just dozens of kilometres west of Madrid became the largest in Spain's recent history and triggered a national emergency.
