Gale-force winds, torrential rain and hail were reported across parts of northern Greece on Wednesday evening as a freak storm took hold.
The storm, which hit the popular tourist peninsula of Halkidiki, left at least six foreign nationals dead, including two children.
Two elderly Czech nationals were killed after their caravan was swept away, while a Romanian woman and an eight-year-old boy were killed after a restaurant roof collapsed.
Two Russian nationals, a man and young boy, were also killed after they were caught under a collapsed tree.
Videos captured by local media showed the storm damage, including vehicles crushed by uprooted trees and debris, and roofs that had been ripped off buildings.
Restaurant fronts were also destroyed in the severe weather.
People living on the peninsula described having never experienced a storm like Wednesday night’s events.
One Facebook user, Despina Chitri, said she had lived in Potidaea for three decades, but it was the first time she had seen such “dramatic moments”.
She shared pictures of debris and objects overturned on her balcony, adding: “We do not have light, our houses took in water, hail, rain, lightning, thunder, destruction.”
