As many as 300 homes have been buried under rubble following a landslide in the Mexican state of Oaxaca.
Heavy rains in the southern state saw a 200 metre-wide sector of mountainside collapse above the town of Santa Maria Tlahuitoltepec earlier today, according to local officials.

Rescue efforts are being hampered by continued bad weather, with the state governor warning as many as 600 people could be trapped under the debris.
“There has been lots of rain, rivers have overflowed and we are having a hard time reaching the area because there are landslides on the roads,” Oaxaca state governor Ulises Ruiz told the Televisa network.
He added local telephone lines had also been cut off.
Oaxaca was hit by an earthquake in June this year. There were no reports of fatalities during the incident.
Rescuers are on route from Mexico City, while emergency personnel have been sent to the town, which is about 50 miles east of Oaxaca City.
Mr Ruiz also confirmed the Mexican army had been mobilised as part of the rescue efforts.
