Scores of people have been evacuated as more than 700 firefighters tackle a major forest fire on the Portuguese Algarve.

The fire has been burning for three days in tinder dry conditions amid a record heatwave affecting Portugal and Spain with temperatures soaring to 46C on Saturday.

The Foreign and Commonwealth Office issued updated travel advice to British holidaymakers on the Algarve, warning that the forest fire had reached the inland town of Monchique, in the Faro district.

“The fire has now reached the town of Monchique, and Portuguese authorities are evacuating affected areas of the town and surrounding areas,” the FCO said.

“If you are in this area, follow the instructions of the Portuguese police and Civil Protection authorities.

“Civil Protection Portugal can be reached on 800 246 246 or www.prociv.pt.

“For your own safety, travel to the Monchique area is not advised under any circumstances until cleared by the Portuguese authorities.

“If you need consular assistance, or you have concerns about family or friends in the area, please call (+351) 21 392 4000 or in the UK (+44) 207 008 1500.”
