Deadly floods hit Mandra
The industrial towns of Mandra, Nea Peramos and Megara, west of the capital Athens, were the most affected.
Many of the dead were elderly people whose bodies were found inside their homes, reports say. Fast-flowing torrents of red mud flooded roads.
At least 37 people have been taken to hospital, the broadcaster said, and some are still missing.
