Mexico's president calls the flooding in Tabasco state "one of the worst natural catastrophes in the history of the country."
Since swollen rivers broke their banks October 28th, floodwaters have damaged the homes of a half million people and cut off entire towns.
Many in Tabasco remain camped out on rooftops or upper floors of their homes to guard against looters but their supplies are running out.
Some desperate residents in Villahermosa broke into shuttered stores and took food and household goods, and police reported detaining about 50 people.
A woman with one nonprofit group that's been handing out aid says people have been fighting over food and water.
The flooding has killed around 10 people. Two more bodies were found yesterday.
