A tornado raged through the northern Mexico border city of Ciudad Acuna early Monday, killing at least 10 people, destroying homes and upending cars and other vehicles.
Rosario Cano, spokeswoman for the interior department of the northern state of Coahuila said 10 people had been confirmed killed so far in the twister, which struck around 6:40 a.m. Central time.
Photos from the scene showed cars with their hoods ripped off, resting upended against the facades of one-story houses.
One car's frame was literally bent around the gate of a house. A bus was seen flipped and crumpled on a roadway.
Ciudad Acuna is a city of about 100,000 across the border from Del Rio, Texas.
Cano said top state officials had set out to review the damage and coordinate response to the disaster.

An evacuation order has been lifted for people living near a reservoir north of Houston after weather improved and work crews made progress shoring up threatened areas along a levee weakened by recent heavy rains.
Montgomery County authorities allowed residents back into their homes in neighborhoods near the Lewis Creek Reservoir late Sunday evening.
County Judge Craig Doyal said he regrets the inconvenience that several hundred residents may have experienced, but he says the decision to order evacuations early Sunday was made based on weather forecasts at the time and in the interest of public safety.
The reservoir serves an Entergy power plant about 50 miles north of Houston. Officials have reported no breaches.

A line of storms stretching from the Gulf of Mexico to the Great Lakes dumped record rainfall on parts of Texas, Oklahoma and other Plains and Midwest states.
The weekend storms spawned a tornado that damaged a Houston apartment complex and caused major flooding that forced at least 2,000 Texans from their homes.
Authorities are blaming three deaths on the storms. Two were in Oklahoma and the last was in Texas, where a man's body was found along the swollen Blanco River.
Among the worst-affected communities are Wimberley and nearby San Marcos in the Central Texas corridor between San Antonio and Austin. Many homes in those communities were damaged or destroyed.
More rain is in the forecast for Monday for a large swath of the nation's midsection.
