MILAN (AP) — Firefighters worked Thursday to put out the remnants of two wildfires on a Sicilian island that forced fashion designer Giorgio Armani and dozens of others to flee their vacation villas overnight.

A photo from the island of Pantelleria showed flames appearing to encroach on Armani’s villa, but the Italian designer’s press office said they stopped short of the property. Armani and guests evacuated to a boat in the harbor.

The head of the region’s civil protection agency, Salvatore Cocina, said arson was suspected in two wildfires that forced around 30 people to seek refuge in boats or on safer parts of the island. Firefighters used Canadair planes to douse the flames, along with ground teams to protect homes. Authorities said no structures appeared to have been lost.

The island’s mayor, Vincenzo Campo, told Italian news agency ANSA that two planes were working on putting out the last flames on difficult terrain and that the wind had dropped off.

“After the great fear of last evening and the night spent at work, Pantelleria is returning to normal,” Campo said. “It seems the worst is over.”

Local officials appealed for any information that would help identify the cause of the blaze, which started in two places a quarter-mile apart.

Pantelleria, located between Sicily and Tunisia, is a popular beach and trekking destination that includes ancient archaeological sites and natural geographic formations.

Scientists say global warming will continue to make weather more extreme and wildfires more frequent and destructive. Much of western Europe saw little rain this summer, and drought conditions coupled with hot weather have fueled destructive forest fires.

So far this summer, wildfires in Spain have blackened more than 1,729,737 acres, the largest area since the European Union started collecting satellite data in 2006.

The EU’s Earth Observation Program said more torrid weather was forecast for Spain as two “disastrous” wildfires burned in the eastern part of the country. The fires in the Mediterranean provinces of Alicante and Castellón have each charred more than 32,123 acres, the EU agency said.

Meanwhile, authorities in Portugal reported that a wildfire burning for almost two weeks in the pine forests of Serra da Estrela national park was brought under control. However, officials warned of weather forecasts indicating a dangerous new heat wave would arrive soon.

High temperatures, strong winds and a severe drought helped sustain the blaze in the park, where deep ravines and steep hillsides make firefighting difficult.

More than 1,100 firefighters remained in the Serra da Estrela, keeping an eye out for hot spots and embers that might be blown into untouched forest, the Civil Protection Agency, a government department, said.

The blaze charred more than 64,000 acres of woodland, according to European Union data — about one-fourth of the park’s area.

On Wednesday, the fire’s perimeter measured around 99 miles, emergency officials said.

Fire officials said that was an indication the country is fighting a “new generation” of wildfires that are harder to stop amid the consequences of climate change.

Temperatures in Portugal were due to start climbing, reaching 102.2 Fahrenheit in inland areas on Saturday, as the country endures its third heat wave of the summer.
