Searchers have found 10 more bodies of victims from twin storms that struck the country's Pacific and Gulf coasts at the same time last month, raising the death toll to 157, Mexico's government said Wednesday.

Statistics sent by civil protection officials to The Associated Press said a total of 155 people had died across the states hit by the storms' heavy rain. But the head of the agency, Luis Felipe Puente, said later Wednesday that the toll had risen to 157.

Nearly 175,000 homes were affected by floods and landslides, mostly in the southern state of Guerrero.

The biggest known tragedy was a mudslide that swept into a remote mountain village in Guerrero and left dozens missing. Only some of their bodies have been recovered.

President Enrique Pena Nieto has ordered an investigation to find which officials gave permits for building homes in banned areas such as riverbeds, which put residents in danger during the storms.
