- Local media have described the flooding as "biblical"
- Hundreds of homes and businesses have been damaged
More than 20 people have been injured and one is missing in a disaster that local media have described as "biblical."
Residents in Mandra, one of the most affected areas, northwest of Athens, have been "trapped in their homes, the water is 1 meter (about 3 feet) high inside some houses, and (they) have no electricity and water," said Mayor Yianna Krikouki.
Speaking on Greek radio, Krikouki said there was "nothing standing in the entire area of Mandra" and the town is "now mourning its lost fellow citizens."
