Greece has suffered 66 wildfires between 6 p.m. Friday and 6 p.m. Saturday local time, according to reports from the media.

State-run AMNA news agency relayed that 52 of them were brought under control, with firefighting teams currently addressing the remaining 14.

Authorities from civil protection highlighted significant ongoing efforts to manage fires in the Kontodespoti area of Evia Island and Sapci (Sapes) in Western Thrace.

The civil protection service has called for extreme vigilance, warning that the risk of fires is "very high," particularly in the Attica region, the Peloponnese peninsula, and central Greece.

This comes after Greek authorities arrested 13 people on Saturday after fireworks launched from a yacht ignited a forest fire on an island near Athens. This incident comes as the country faces a new season of deadly summer fires.

Record-breaking temperatures

The mayor of Hydra expressed outrage after the fire broke out late on Friday and vowed to take legal action against those responsible.

Hydra's firefighting team reported on Facebook that the latest blaze was "caused by fireworks launched from a boat and burned the only pine forest on the island, located in a difficult-to-access area with no roads."

No details on the suspects have been provided. Greece has toughened its penalties for arson, with perpetrators now facing up to 20 years in prison and fines of up to 200,000 euros (£169,000).

Greece is bracing for a difficult summer, as authorities caution that strong winds and high temperatures have heightened the danger of wildfires.

After experiencing its warmest winter on record, Greece recorded its first heatwave of the year last week, with temperatures soaring above 44°C (111°F) in some locations.

On Friday, firefighters battled wildfires fueled by three days of fierce winds. These fires have claimed at least one life, as a 55-year-old man collapsed and died while fighting flames near his village.
