Crushed cars and household appliances strewn outdoors greeted people who returned home Thursday as flood waters from the Rio Grande rolled farther downstream.
The death toll from the flooding, which was blamed on a weekend tropical storm, rose to 17 Thursday after authorities confirmed finding three more bodies on both sides of the Rio Grande.
Two of the bodies were found in Mexico. Of those killed, five were in Mexico and 12 in Texas.
The Rio Grande, which forms the border between the United States and Mexico in southwestern Texas, was expected to flood farther downstream. Damage was not expected to be as heavy since communities further to the south were at higher elevations.
Dozens of people were missing in this city of 34,000, and search teams were looking for other victims in piles of debris. Authorities believed many of the missing were not dead, however.
Thousands of people were in camp shelters across the river in Ciudad Acuna, Mexico. The Mexican news agency Notimex said the flooding damaged houses in 20 neighborhoods.
