A flash flood struck a suburb in northern Athens following a squall, with the Greek capital's fire department receiving 140 calls for assistance and to pump water from flooded homes and businesses.
Fire crews headed to an open-air parking lot in the suburb of Maroussi on Thursday to see if there were any people trapped in cars that were bobbing in a suddenly created muddy lake.
Authorities urged drivers to avoid the area and shut down a side road off the main highway leading north out of Athens.
