Turkish authorities on Thursday began investigating the cause of a string of forest fires in Turkey's Mediterranean and southern Aegean regions, including two near the coastal resort town of Manavgat that killed three people and sent over 50 others to the hospital as homes burned down.

A wildfire that broke out Wednesday in Manavgat, in Antalya province, and was fanned by strong winds and scorching temperatures, was largely contained, Agriculture and Forestry Minister Bekir Pakdemirli said. But another fire that started overnight and swept through the district of Akseki, 50 kilometers north, kept firefighters engaged.

Three people were killed in those fires, and authorities evacuated nearly 20 neighbourhoods or villages.

The Antalya region is a popular vacation destination for tourists from Russia and other parts of Europe.

Fires also broke out Thursday in 16 other locations, including in the İçmeler region, close to the resort of Marmaris, 320 kilometers west of Antalya, that briefly threatened holiday homes and hotels. A hotel in the Aegean beach resort of Guvercinlik, near the town of Bodrum, was also evacuated, Pakdemirli said.

In the resort filled region of İçmeler, known as the Turkish Riviera, the fires were visible from busy summer hotels.

Mehmet Oktay, the mayor of Marmaris, told NTV television that he could not rule out "sabotage" for the fire there, while Fahrettin Altun, the Turkish presidential communications director, said "comprehensive investigations were ... launched into the cause of the fires."

"Those responsible will have to account for the attacks against nature and forests," Altun said on Twitter.

Pakdemirli said a total of 53 forest fires were reported in the country on Wednesday and Thursday, but that most of them had been brought under control. Three planes, 38 helicopters and some 4,000 firefighters were deployed to battle the blazes, he said.

Wildfires are common in Turkey's Mediterranean and Aegean regions during the arid summer months, although some previous forest fires have been blamed on arson or outlawed Kurdish militants.

The dead in the fires in Antalya included a 82-year-old man in Akseki's Kepezbeleni neighbourhood, where 80 per cent of the houses were incinerated, the district's governor, Volkan Hulur, told Anadolu.

The Turkish government's Disaster and Emergency Management Presidency, or AFAD, said in addition to the three dead, at least 112 people were affected by the fires, including 58 who were hospitalised, mostly for smoke inhalation.

Authorities also rescued 10 people stranded at a restaurant near Akseki.

Pakdemirli said more than a 1,000 farm animals perished while 600 hectares of agricultural land and 50 hectares of agricultural glasshouses were destroyed in Manavgat. He said 10 intubated intensive care patients at Manavgat's state hospital were transferred to other hospitals as a precaution.

Patrizia Under, who was vacationing in the İçmeler area, said she was bathing in the sea with friends when she noticed a fire blazing on a mountainside behind a residential area that engulfed the air with smoke.

"We got out of the sea and got into our car and left," she said by telephone, as she waited for authorities to allow people to return to their homes.
