Residents were evacuated on Saturday as a wildfire which started in mountainous forests in the eastern Aegean island of Lesbos threatened properties at the beach resort of Vatera.
Thick billowing smoke fanned by strong winds could be seen in the area. One fleeing resident told state TV that her home was on fire.
