Rescue crews were searching Wednesday through charred homes and cars for those still missing after the deadliest wildfires to hit Greece in decades decimated seaside areas near Athens, killing at least 79 people and sending thousands fleeing.

There was no official indication as to how many people might be missing, and some took to social media and Greek television stations with appeals for information on their loved ones.

Survivors described dramatic scenes of people fleeing to beaches and being forced to swim out to sea despite gale-force winds and high waves to escape choking smoke and flaming pine cones raining down into the water.

Fire service spokeswoman Stavroula Malliri said the death toll had increased by five to 79. There were fears it would increase further as rescue crews gradually went through the hundreds of burnt homes, while others searched the coastline and the sea.

More than 280 firefighters were still in the area to the northeast of Athens in the wider Rafina area, dousing the remaining flames to prevent flare-ups. A further 200 firefighters backed up by a water-dropping helicopter were tackling the second forest fire west of the capital, near Agioi Theodori, where local authorities pre-emptively evacuated three communities, a children鈥檚 summer camp and three monasteries overnight, according to the fire department.

Flags across Greece flew at half-staff after the prime minister declared three days of national mourning.

The two fires on either side of the Greek capital started Monday within hours of each other, fanned by gale-force winds that hampered firefighting efforts.

The speed with which the blaze northeast of Athens spread took many by surprise, and is believed to have contributed to the high death toll.

鈥淲e couldn鈥檛 see any fire. The fire came suddenly. There was so much wind, we didn鈥檛 realize how it happened,鈥� said Anna Kiriazova, 56, who survived with her husband by shutting themselves in their house instead of trying to flee through the flames.

Kiriazova said they used a garden hose to douse their house in the Mati area near Rafina with water, and credited the fact that their window frames were metal instead of wood for their home being spared.

鈥淲e shut ourselves in the house, we closed the shutters, we had towels over our faces,鈥� she told The Associated Press. 鈥淭he inferno lasted about an hour. I have no words to describe what we lived through.鈥�

Her 65-year-old husband, Theodoros Christopoulos, said the couple decided to take shelter indoors because the narrow roads were jammed.

鈥淭here was a great panic because the whole street was blocked by cars,鈥� Christopoulos said. 鈥淪houting, hysteria, they could see the fire was coming with the wind. It already smelled a lot, the sky was black overhead and in no time at all the fire was here.鈥�

Hundreds of others abandoned cars and fled to nearby beaches, from where they were evacuated hours later by coast guard and private boats. Dozens swam out to sea despite rough weather to escape the intense heat and choking smoke.

One woman told state television she fled into the sea with her daughter and grandchildren, aged 13 and 15, and they were forced to swim out beyond the shallows along with many others who had sought shelter on the beach.

鈥淭he sea was burning, the flaming pine cones were falling into it,鈥� said the woman, who gave only her first name, Mary. 鈥淲e couldn鈥檛 stay (in the shallows).鈥�

Thick smoke blacked out the sky, and the group quickly lost their bearings.

鈥淭he sky was smoky and black, and the sea stormy,鈥� she said. 鈥淭here were a lot of waves, huge waves 鈥� they were coming like mountains over us.鈥� In desperation, her grandchildren shouted for help at firefighting planes flying overhead.

After more than four hours at sea, the group was picked up by a fishing boat with an Egyptian crew, which went on to pick up others from the sea, including the body of at least one person who had drowned, the woman said.

With the number of missing unclear, authorities appealed for people to call them if they were searching for loved ones. Some people also turned to Greek television and radio stations, asking for information from the public for relatives they hadn鈥檛 heard from since the blaze.

The story of one man desperately searching for his children highlights the plight of many families looking for relatives.

Yiannis Philipopoulos appeared on television early Wednesday appealing for help to locate his missing twin daughters, who he said he had spotted on television footage arriving in the port of Rafina in a fishing boat during the evacuation of people from beaches overnight Monday to Tuesday.

Yiannis Philipopoulos said he and his wife recognized 9-year-old Sophia and Vasiliki in the news footage after spending a fruitless day searching hospitals and giving DNA samples at the Athens morgue. He had contacted police, who were helping search for the girls.

Philipopoulos said the girls had been with his parents, of whom there was no sight in the footage. Speaking on television stations Skai and Alpha, he said the images gave him hope his children were alive, and urged anyone with information to contact him.

The footage showed two girls among other people, many clad just in swimsuits, disembarking from the fishing boat. Philipopoulos said he went with police to the TV station and saw the footage in higher resolution, and was sure the children were his daughters. But he had not heard from them since the fire.

The captain of the fishing boat said authorities had recorded the names of rescued people as they disembarked. The names of the two girls, however, appeared not to be among them.
