Flash Flood Kills Scores of Moroccans 

Casablanca, Sept. 24

UPI-A flash flood swept across the coastal plain about 100 miles southwest of here, killing scores of villagers in a market place yesterday morning. Reporters from the area said 75 bodies had been counted, and dozens of people were missing.

The flood followed heavy rains that filled the coastal plain’s dry creek beds to overflowing. The flood crest, several feet high, hit the village of Khemis Nagua at mid-morning yesterday as farmers from the surrounding area joined townsfolk in an open market place.

The roaring water swept the village’s flimsy dwelling places, the market sheds, shoppers, cattle and farm implements for almost as soon as it started, the reporters said, as the crest swept out to sea. Rescue workers quickly moved into the area from Safi, about 25 miles further south.
