Floodwaters unleashed by Hurricane Georges washed away much of a low-lying town in Haiti, killing at least 85 people, U.N. civilian police said. Others were missing and feared dead.

The discovery of more flood victims in Fonds Verrettes, 50 miles east of Port-au-Prince, the capital, pushed the nation's storm death toll from 87 to 147, the government said Tuesday.At least 40 others were missing in Haiti, the Western Hemisphere's poorest nation.

Rains began falling in the town, which was built on a dry river bed, when Georges was pounding the neighboring Dominican Republic on Sept. 22.

Rising waters sliced through the streets that night, demolishing 100 houses and damaging 200 more, U.N. police instructor Hubert Ouellette said.

"A lot of people were asleep in their homes, covered by darkness. The water built up fast and strong, even moving rocks," he said Tuesday.

In some places the flood cut a trench 35 feet deep in the river bed, undermining the foundations of buildings, he said.
