"MARIANA, Brazil -- "Three days after a massive mudflow and flood caused by ruptured dams at an iron ore mine, Brazilian authorities are still struggling to determine a cause or even recover the bodies of as many as 28 people possibly swept away in the torrent.

The disaster in the mineral-rich southeastern state of Minas Gerais, directly north of Rio de Janeiro, has prompted a rescue and salvage operation involving about 500 people, many of whom are still searching with the help of dogs and special equipment for victims along the floodplain downstream from the dams.

Authorities late Sunday recovered two more corpses of possible victims that if confirmed would raise the death toll so far to four. Of the 28 people listed as missing late Sunday, 13 were mine workers."
