Greece is sweltering in a heatwave that is searing much of southern Europe.

The country has become particularly vulnerable in recent years to summer wildfires, which are fuelled by strong winds, drought and high temperatures linked to climate change.

Local media said around 1,500 people had to be evacuated because of the blaze, which broke out on Wednesday evening.

"Evacuations took place in numerous hotels and tourists were safely transferred to a closed gymnasium in the municipality of Ierapetra," vice-prefect Yannis Androulakis told TV channel Mega, referring to the holiday town in the southeast.

He said the authorities acted because water bomber planes could not reach the affected areas overnight.

"At the moment, there are three active fronts," Androulakis said. "Because of the strong winds, the fire has progressed quite rapidly."

Around 270 firefighters, 10 helicopters and drones have been deployed to tackle the blaze, said Vassilios Vathrakoyannis, a spokesman for the fire service.

They include reinforcements sent in from the capital, Athens.

"There are still a number of different fronts. The fire is burning scrubland and crops," he said.

"The winds are very strong -- up to nine on the Beaufort scale."

- Uneven, arid terrain -

Crete, Greece's largest island, has an arid, uneven landscape criss-crossed by gullies, making it difficult for firefighters to tackle the blaze.

The fire has damaged both houses and crops in fruit and vegetable greenhouses, local media said.

Like the rest of Crete, Ierapetra -- a seaside resort with a population of 23,000 -- takes in thousands of tourists in the summer.

Vathrakoyannis said the authorities would assess the extent of the damage once the fire had been brought under control.

He stressed the risk of fires was "considerable" in July, the hottest month of the year in Greece.

Until now, Greece had been more or less spared the heatwave that has gripped other parts of southern Europe.

The country recorded its hottest ever summer last year when 45,000 hectares were torched, according to WWF Greece and the Athens National Observatory.

In terms of surface area destroyed, 2023 was the worst on record.

Nearly 175,000 hectares were obliterated and 20 people died during a series of prolonged heatwaves when temperatures rose in places to 46 degrees Celsius (115 degrees Fahrenheit).
