Belgian wildfire approaches Germany despite rain as Greece probes deadly blaze

One of Belgium's biggest-ever wildfires blazed out of control Monday even as cooler weather and rain eased conditions for firefighters, while in Greece a fire briefly flared up near the main airport on the outskirts of Athens.

The fire in Belgium could continue for months underground in peaty soil and sporadically flare up, according to a fire ranger.

Europe is sweltering through one of its hottest and driest summers on record, which a recent study said has been fuelled by climate change.

Belgium's King Philippe interrupted his summer vacation to visit emergency services fighting the wildfire in the eastern High Fens, about eight kilometres from the German border, as it spread east after moving into a pine forest on Sunday.

The fire in Liège province has burned an estimated 30 square kilometres, leaving blackened trees and smouldering ground.

While the fire did not grow significantly, due in part to favourable winds, it remained out of control in areas inaccessible to ground crews, the Wallonia region said in an update.

Some 500 firefighters were aided by aircraft sent from Norway, Sweden, Germany and the Netherlands and local police with drones after a cold front brought overnight rain.

Farmers were helping supply water to firefighting efforts, regional officials said. Helicopters emptied huge sacks of water over the flames as smoke billowed from forests.

"We managed to maintain the fire where the firemen are situated, but there's still a place which is totally inaccessible, where the fire is still going on in the direction of Monschau in Germany," said Nicolas Yernaux, the spokesperson for the Wallonia regional public services.

He said overnight rains helped contain the blaze and dampen the possibility that smouldering fires will flare up again, but he said they did not significantly impact the centre of the fire.

A forest ranger from the region told The Associated Press that the blaze could continue for months underground because of the peaty soil.

"What we see here is that the grassland has burned and the fire has gone into the soil to a certain depth, into the peat, and it is still burning," said Yves Pieper. "It can go down very, very low in the peat layer."

He said the fire can continue smoldering largely unseen underground for weeks or months before flaring up again, noting that new flames had already appeared nearby.

Precautionary evacuation orders remained in effect for hundreds of residents.

Veterinarian Hugues Guyvot, who was involved in animal rescue efforts, said large animals were able to flee but smaller ones like frogs and mice likely burrowed and were baked underground in a landscape of peat bogs.

"Maybe it will take decades to recover from this fire," he said.

Tourists have left the region and cancelled reservations, said Thomas van Sante, the owner of the Mont Dragon hotel near the park where the fire was raging.

"There's rain now, but it is not enough," van Sante said.

Precautionary evacuation orders remained in effect Monday for hundreds of residents.

Greece quickly extinguishes fire near main airport

In Greece, fire department investigators examined the area on the island of Salamina where a fast-moving wildfire on Sunday killed two people, injured another nine and destroyed several homes. The island lies just west of the Greek capital.

New wildfires broke out elsewhere Monday. Dozens of firefighters along with two water-dropping planes and two helicopters raced to tackle one in Spata, an area east of Athens that includes the main international airport. The fire department said the blaze was contained within 30 minutes.

Separately, the fire department said an 80-year-old man was arrested in the northern town of Kavala on arson charges for allegedly deliberately setting fire to dried vegetation.

The arrest was among 302 fire-related arrests since Jan. 1 in Greece, including 31 for deliberate arson and 271 for negligence that sparked fires, the department said.

In southwestern France, authorities said a fire in the Landes region was under control after four days of battling the flames, allowing about half of the evacuated residents to begin returning home.

More than 600 residents evacuated last week as the fire burned about 17 square kilometres during a prolonged spell of extreme heat. Some respite was on the way Monday as temperatures began to drop.

French Prime Minister Sébastien Lecornu said the state would provide a 12 million-euro aid package to Gironde and Landes, the regions hardest hit by the wildfires, to help rebuild homes and support affected businesses, including in Le Porge, where 183 homes were destroyed in a massive blaze last month.

Meanwhile in Croatia, four people are suspected of deliberately starting as many as 10 fires in the region around the coastal town of Zadar, a major tourism hub on the Adriatic coast.

The suspects were questioned by an investigative judge following their arrest on Saturday on a tip from residents.

The four are suspected of starting fires on Aug. 14 and 15 with an aim to "endanger lives and valuable property and inflict damage on a large number of residents in Zadar county," police said in a statement. There was no word on a possible motive. Police said they were assessing the extent of the damage caused.
