Up to 1,000 people may have been trapped by a landslide in the southwestern Mexico state of Oaxaca, Gov. Ulises Ruiz said Tuesday morning.
A hill about 650 feet wide (200 meters) collapsed early Tuesday, sending tons of mud atop up to 300 houses, Ruiz told CNN affiliate Televisa.
Rescue officials, heavy machinery as well as police and military authorities were on their way to the scene, Ruiz said.
"We expect to get there in time to rescue these people," he said.
