ATHENS — Greek Prime Minister Kyriakos Mitsotakis on Thursday described the devastating wildfires that burned across the country for more than a week as the greatest ecological catastrophe Greece had seen in decades.

The fires broke out as the country roasted during the most intense and protracted heat wave experienced since 1987. Hundreds of wildfires erupted across the country, stretching Greece's firefighting capabilities to the limit and leading the government to appeal for help from abroad. Hundreds of firefighters, along with planes, helicopters and vehicles, arrived from 24 European and Middle Eastern countries to assist.

"We managed to save lives, but we lost forests and property," Mitsotakis said, describing the wildfires as "the greatest ecological catastrophe of the last few decades."

Speaking during a news conference in Athens, his first since the fires broke out, Mitsotakis said authorities had faced around 100 active blazes each day. By Thursday, the situation was much improved, with most large wildfires on the wane.

But the prime minister warned the danger of more blazes was still present.

"We are in the middle of August and it's clear we will have difficult days ahead of us" until the main season during which fires break out is over, he said.

"The climate crisis — I'd like to use this term, and not climate change — the climate crisis is here, and it shows us everything needs to change" he said, adding he was ready to make the "bold changes" needed. 

"This is a common crisis for all of us," he said.

Several Mediterranean countries have suffered intense heat and quickly spreading wildfires in recent weeks, including Turkey, where at least eight people have died, and Italy. In Algeria, wildfires in the mountains have killed at least 65 people.

Worsening drought and heat – both linked to climate change – have also fueled wildfires this summer in the Western United States and in Russia's northern Siberia region. Scientists say there is little doubt that climate change from the burning of coal, oil and natural gas is driving more extreme events.

Greece's largest fire broke out on the country's second-largest island of Evia on Aug. 3 and was still smoldering on Thursday, after having destroyed most of the island's north.

More than 50,900 hectares were damaged in northern Evia, according to mapping from the European Union's Copernicus Emergency Management Service. Entire mountains of mainly pine forest have been reduced to wastelands of blackened stumps, while olive and fig tree plantations and vineyards were also destroyed.

More than 850 firefighters, including hundreds from the Ukraine, Romania, Serbia, Slovakia, Poland and Moldova, were continuing efforts to prevent flare-ups in the area, assisted by four helicopters and three aircraft, including the massive Ilyushin 11-76 water-dropping planes sent by Russia.

The government prioritized protecting lives in its fire response, issuing dozens of evacuation orders for villages in the path of the flames. In that respect, the policy appears to have worked. One volunteer firefighter died while working in an area north of Athens hit by a major fire, after being hit by a falling electricity pole. Four volunteer firefighters have been hospitalized with burns, including two in critical condition in intensive care.

Greek authorities had been anxious to avoid a repetition of the summer of 2018, when a fast-moving wildfire engulfed a seaside settlement near Athens, killing more than 100 people, including some who drowned trying to escape by sea. 

But the current tactic of evacuation orders has come under criticism by many residents and local officials in areas affected by this year's fires, who have argued the orders were premature. They point to those who ignored the evacuation messages, staying behind to fight the flames and managing to save their homes. 

"We managed to protect thousands of people. But we lost forests and property," Mitsotakis said during his press conference. "And we are here to talk about everything … (including) where nature found us unprepared."

The government has also come under criticism for not deploying enough firefighting planes and helicopters, and not sending them soon enough, particularly to Evia. Authorities have countered that the aircraft were flying wherever possible, but that the entire firefighting fleet cannot be airborne at the same time, as some need to land for essential servicing.

Asked about the cause of the fires, and whether an organized campaign of arson was suspected, Mitsotakis said it was "certain that some of the fires in the last few days were the result of arson." Several people have been arrested over the past few days on suspicion of attempting to start fires, including some who are accused of doing so deliberately.

However, he added it was unclear whether this was a result of an organized plan, and noted that the hot, dry conditions had aided the spread of wildfires.
