Rescue workers on Friday found the body of another Brazilian killed after a dam ruptured, raising the death count to at least five with four people still missing.
Authorities in the northeastern state of Piaui reduced the count of missing from a previous estimate of 11 after seven people were located.
Civil defense officials also said Friday that water from the dam destroyed part of a highway 53 miles down river from the small farming city of Cocal where the dam is located.
Raging torrents cascaded into Cocal, population about 25,000, Wednesday night. Eighty people suffered minor injuries, nearly 3,000 were left homeless and the waters carried away cattle and inundated crops.
Floods in Brazil have caused chaos since April from the Amazon to the Atlantic Ocean — killing at least 59 people and displacing more than 423,000.
The heavy rains are blamed on an Atlantic Ocean weather system that normally moves away in April but hasn't budged this year. Meanwhile, southern Brazil has been hit by a drought that has severely affected agriculture.
