A tornado has raged through the northern Mexico border city of Ciudad Acuna, 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 tornado, which struck at around 6.40am local time.
Photos from the scene showed cars with their bonnets ripped off, resting upended against the facades of one-storey houses.
One car's frame was bent around the gate of a house, while a bus was seen flipped and crumpled on a roadway.
Ciudad Acuna is a city of about 100,000 people across the border from Del Rio, Texas, in the US.
Ms Cano said top state officials had set out to review the damage and co-ordinate the response to the disaster.
