Il Nuovo Postiglione - Wildfire rages on Crete as strong winds hamper firefighting

"The situation around Rethymno is better," a fire department spokesperson told AFP.

But the blaze "has not yet been contained, there are still many hotspots," he added.

Fires are also burning on the islands of Paros, Kalymnos and Andros in Aegean sea but "the situation is better", according to the fire service.

About 4,500 hectares (11,120 acres) had been scorched on Wednesday and Thursday south of the tourist town of Rethymno, according to meteo.gr, the weather service of the National Observatory of Athens, citing an analysis of satellite imagery from the European Union's Copernicus programme.

Strong, persistent winds, combined with the area's rugged terrain, continued to complicate firefighting operations, authorities said.

Across Greece, firefighters and civil protection services have been placed on general alert, fire brigade spokesman Vassilis Vathrakogiannis said at a briefing on Thursday.

Many parts of the country, including the Athens region, Crete, numerous Aegean islands and parts of the Peloponnese, faced a "very high" wildfire risk on Friday, the second-highest level on Greece's five-point scale, according to Greek civil protection.

Greece's geography, made up of hundreds of islands, complicates the rapid deployment of emergency responders, Vathrakogiannis said.

Additional firefighting resources have been dispatched to Crete.

"Strong winds and dense smoke are creating conditions of near-zero visibility and severe turbulence, making aerial water drops extremely difficult, if not impossible," he said, particularly in Crete.

Greek authorities on Wednesday ordered the evacuation of around 8,000 residents and tourists from the coastal resort of Agia Galini.

Most evacuees have since returned to their homes and hotels as Crete's peak tourist season continues.

Prime Minister Kyriakos Mitsotakis warned on Thursday that Greece, which had largely avoided the severe heatwaves and major wildfires seen earlier this summer in countries such as France and Spain, was entering a challenging period.

"August ... is traditionally a difficult month," he said.

"Conditions are expected to worsen further in the coming days," the fire department spokesperson also warned.

Three firefighters have died this week while battling wildfires in Crete and the Peloponnese, according to Greek authorities.
