An out-of-control wildfire on the Spanish Canary island of Tenerife has burned thousands of acres and affected some 7,600 people who are either evacuated or confined, regional president Fernando Clavijo said on Thursday.

He said some 250 firefighters and members of the Spanish army are tackling the blaze, located in the north of the island.

Mr Clavijo said the fire had a perimeter of nearly 30 kilometres (19 miles).

He told reporters: “This is probably the most complicated blaze we have had on the Canary Islands, if not ever, at least in the last 40 years.”

He said extreme temperatures in the island added to “specific meteorological conditions” caused by the fire that turned the area into a virtual oven.

The seven-island archipelago is located off the north-west coast of Africa and south-west of mainland Spain.

Spanish authorities said their main goal is to contain the fire and prevent it from reaching more populated areas. The island’s main town, Santa Cruz, is 20 kilometres (12 miles) from the flames.

The wildfire is threatening six municipalities and some 7,600 residents in the area have been evacuated or ordered to stay indoors due to hazardous air quality.

Mr Clavijo said firefighters were working day and night but the fire remained “out of control.”

The blaze, which started on Tuesday night, is centered on a craggy, mountainous area, which is difficult for emergency brigades to gain access to.

Temperatures in the Canary Islands peaked at more than 40C (104F) in recent days. Temperatures are set to rise again on Saturday.

The fire could become Spain’s worst blaze so far this summer, as the country suffers another year of severe drought.

More than 2,000 people were evacuated in a wildfire on the nearby La Palma island last month that affected some 4,500 hectares (11,000 acres).

Wildfires have burned almost 64,000 hectares (158,000 acres) in Spain in the first seven months of the year, according to Spanish government data. That’s the third highest figure in the last decade.

Spain accounted for almost 40% of the nearly 800,00 hectares (2 million acres) burned in the European Union in 2022, according to the European Forest Fire Information System.
