Greek firefighters are battling a large wildfire south of Athens as the country faces its first major heat wave of the summer, with temperatures nearing 40°C and strong winds fuelling the flames.

The blaze broke out near the coastal town of Palaia Fokaia, around 40 kilometres from the capital, damaging several holiday homes and burning forested areas.

Authorities said the fire is spreading rapidly due to extreme heat and wind. An arson investigation unit has been deployed, but the cause remains unknown.

More than 130 firefighters, backed by 80 fire engines, are on the ground, supported by 12 water-dropping planes and 12 helicopters. Volunteers from the Hellenic Red Cross also assisted with evacuations of people from their homes.

Police have evacuated at least 40 people from the area. Eleven tourists were rescued from a holiday home, while two coast guard boats and nine private vessels remain on standby for possible sea evacuations.

The civil protection agency sent emergency text alerts urging residents to leave. No injuries have been reported, but ambulances are on standby.

Wildfire risk remains high across much of Greece, including the greater Athens area and several Aegean islands. Authorities warn that conditions on Friday will remain dangerous before a possible drop in temperatures.

Earlier this week, it took firefighters four days to control a major blaze on the island of Chios.
