VARIBOBI, Greece — Greece evacuated people in boats from an island beach Wednesday amid heavy smoke from a nearby wildfire, and fire crews fought elsewhere to keep flames away from the birthplace of the ancient Olympic Games as the country sweltered under a record heat wave.

With more than 100 wildfires burning in Greece, the European Union sent assistance to it and other southeast Europe countries grappling with huge wildfires.

The help came a day after another major blaze burned more than 100 homes and businesses near the Greek capital of Athens.

Civil Protection chief Nikos Hardalias said 118 wildfires broke out over the past 24 hours and warned that even worse days could lie ahead for the hard-pressed fire service.

“We are making a titanic effort on many fronts,” he said at a news briefing. “According to our threat forecasts, tomorrow, too, is expected to be a difficult day ... The toughest part lies ahead of us, the next days and weeks will be even harder. Our key target is to protect human lives.”

Evacuations were taking place in Greece’s southern Peloponnese region due to a major fire near ancient Olympia — where the Olympics were held every four years from 776 B.C. for more than a millennium.

The adjacent town of Ancient Olympia was evacuated, with another seven nearby villages.

The area was ravaged by wildfires in 2007 that cost dozens of lives but spared Olympia’s ruined sports venues and temples.

The mayor of the nearby town of Pirgos said a strong firefighting cordon had been placed around the verdant site, one of the most beautiful in a country teeming with antiquities.

“I think the site’s security is at a satisfactory level,” Panagiotis Andonakopoulos said.

The coast guard evacuated about 90 people stranded on a beach near the northern village of Rovies on the island of Evia. Private boats helped in the operation. Media reports said three firefighters suffered burns. Several homes were burnt as well as swaths of forest.

Temperatures in Greece reached 113 degrees Wednesday in what authorities described as the worst heat wave since 1987.

Neighboring countries face similar conditions, fueling deadly wildfires in Turkey and blazes in Italy and across the Mediterranean region.

Officials in Albania said one person died of smoke inhalation near the southern city of Gjirokaster, where wildfires caused hundreds of residents to flee.

An EU disaster response group said firefighters and water-dropping planes were being sent from EU members to Italy, Greece, Albania and North Macedonia.

“Following the situation with great concern. European solidarity is at work to fight these terrible fires,” EU Commission President Ursula von der Leyen wrote in a tweet.

The heat wave is forecast to hover over Greece and Turkey until the end of the week.
