MARMARIS, Turkey (Reuters) - Firefighters using planes and helicopters, and locals with buckets of water, battled wildfires raging for a sixth day near southern resorts in drought-hit Turkey and the government faced fresh criticism of its handling of the disaster.

Seven fires were still burning on Monday, fanned by temperatures above 40 degrees Celsius (104°F), strong winds and low humidity, Forestry Minister Bekir Pakdemirli said.

Huge flames engulfed trees on a hillside near the coastal resort of Marmaris, images filmed by Reuters showed, while drone footage revealed a grey landscape nearby where fires had left smouldering buildings and blackened tree trunks.

While 16 planes and 51 helicopters tackled the blazes across a swathe of southwest Turkey, villagers carrying water containers up a hill to fight a fire near Marmaris said the government was not doing enough to help them.

"We are here as the entire village, from the locals to others. We didn't run or anything, so the government must see this and also not run away. It must send some of its planes here," a woman called Gulhan told Reuters.

The heatwave exacerbating the fires comes after months of exceptionally dry weather in Turkey's southwest, according to maps issued by meteorological authorities.

Data from the European Forest Fire Information Service showed there have been three times as many fires https://tmsnrt.rs/3fiKsVF as usual this year, while the 136,000 hectares burnt were almost three times the area burnt on average in an entire year.

Engin Ozkoc, a senior figure in the main opposition CHP, called on Pakdemirli to resign for failing to adequately prepare.

"OUR TURKEY IS STRONG"

"You don't deserve that ministry. You didn't foresee this and buy firefighting planes," he said, criticising the amount of aerial resources available.

The European Union said it had helped mobilise three fire-fighting planes on Sunday. One from Croatia and two from Spain joined teams from Russia, Iran, Ukraine and Azerbaijan.

President Tayyip Erdogan's communications director, Fahrettin Altun, rejected criticism of the government's handling of the fires and condemned a social media campaign calling for foreign help.

"Our Turkey is strong. Our state is standing tall," Altun said on Twitter, describing most information about the fires on social media as "fake news". "All our losses will be compensated for."

Eight people have been killed in the wildfires, but there were no reports of further casualties on Monday.

Since Wednesday, thousands of people have been evacuated from their homes and some tourists have left their hotels, although Tourism Minister Mehmet Ersoy said holidaymakers had returned within hours.

The wildfires are another blow to Turkey's tourism industry following the COVID-19 pandemic.

Bulent Bulbuloglu, head of the South Aegean Hoteliers Association, said 10% of reservations had been cancelled in Bodrum and Marmaris. Others had cut their visits short.
