Officals in Mexico have revised downwards their figures for the number of deaths in several landslides that have hit Oaxaca state, but the situation remains confused as several of the affected areas are completely cut off.
Seven people have been confirmed dead, with a further 100 missing, although another official source said 400 people were unaccounted for.
The worst landslides hit a remote area of southeastern Mexico, washing away roads and making the arrival of rescue workers almost impossible.
Diggers are frantically trying to clear paths and rebuild roads so teams can get in, assess the damage and find those missing.
For the moment no bodies have been found, but an entire hillside fell on the town of Santa Maria Tlahuitoltepec, whose residents were asleep at the time, and the casualty figures could be revised again as more information comes in.
Hundreds of soldiers, police and rescue workers have been mobilised to deal with the disaster, many making their way to the area on foot.
