Greece is in three days of national mourning after at least 79 people died when fires ripped through villages near the Greek capital.
People became trapped in homes and vehicles when fires were sparked west of Athens, near the town of Kineta, and another to the northeast near the port of Rafina.
High winds spread the fire on Monday night and trapped many people in homes and vehicles and forced others into the water as they attempted to flee from the deadly flames.
Mayor of Mati Elias Psinakis told BBC News: “We are still counting because we didn’t find yet all the dead. We are missing 40 people, at least.
“And we don’t know how many are drowned because they jumped to the sea and it was very windy.”
Irish man Brian O’Callaghan-Westropp, who was on his honeymoon in Greece, is still missing and his wife is being treated in hospital.
The fires have left at least 79 people dead, of which four were thought to have drowned as they tried to escape.
One of the youngest victims was thought to be a six-month-old baby who died of smoke inhalation.
The fatalities also include 26 bodies found huddled in the garden of one seaside villa in Mati, according to Red Cross officials.
drone footage from Alexis Alexiou of Flygreecedrone shows the path of destruction caused by the devastating fire.
All that is left of the scorched ground is seared trees and crumbling walls of homes that have been almost completely wrecked by the fire.
BBC correspondent Richard Lister said: “It is a valley of death. The fire raced through these woods towards the town of Mati, leaving a scorched wasteland behind it.
“Much of the town is now a ghostly ash-filled ruin.”
“It burned our backs and we dove into the water.
“It reminded me of the eruption at Pompeii, exactly that.
More than 1,000 people thought to have lost their homes, according to BBC News.
Many people fled to the water and waited more than five hours before the coastguard came and rescued them.
Another Mati resident said: “It’s a huge disaster.
“Sparks were falling on my dress and would have set us alight but we managed to get down to the port in time and stayed there until dawn.”
