Hundreds of firefighters in Greece are struggling to control two new blazes that broke out near Athens on Monday, with a care home and several villages north-west of the capital being evacuated. On Tuesday, about 330 firefighters, including 143 from Poland, with 115 vehicles were battling a blaze in Vilia, about 60 kilometres north-west of Athens, with support from five water-dropping planes and six helicopters. Authorities have called for the evacuation of at least four nearby villages. Hundreds of wildfires have hit Greece this month, with blazes also causing devastation in Italy, Spain and Turkey as the Mediterranean region faces a heatwave. Greek Prime Minister Kyriakos Mitsotakis has linked the fires to the "climate crisis". Firefighters battled a new blaze near the Greek port city of Lavrio, south-east of Athens, as helicopters and planes dropped water on the flames. Residents from three nearby villages were ordered to move to safety. Authorities said the fire reached several houses, but the extent of the damage was unclear. The sky in Athens was again clouded with smoke. "The fire front is large and the winds in the area are very strong. This is a very flammable pine-covered area," Thanasis Avgerinos, deputy governor of the East Attica region, told AFP. Firefighters are battling to keep the flames away from a national park in the southern Sounion region. Authorities say it will then be extremely difficult to control the blaze if it reaches the park. In recent weeks wildfires have destroyed homes, property, pine forests, wildlife and livestock across more than 1,000 square kilometres of land. The island of Evia, about 120 kilometres north-east of Athens, has paid the heaviest price, with more than half of its land burnt. The Peloponnese peninsula, about 300km south-west of Athens, and the northern suburbs of the capital were also heavily affected by about 600 fires, which were at last brought under control on Friday. Mr Mitsotakis said the fires offered a dire warning. "The climate crisis tells us everything must change," he said. As global temperatures increase, heatwaves are predicted to become more frequent and intense, and their effects more widespread, scientists say. Meanwhile, deputy civil protection minister Nikos Hardalias, who has been co-ordinating the firefighting, suffered an "ischaemic episode" and required a heart operation, a hospital said on Monday. Mr Hardalias, 52, will continue to be monitored at the cardiological clinic, it said. Secretary General for Civil Protection, Vassilios Papageorgiou, will step in until Mr Hardalias recuperates, the Greece's civil protection said.
