A strong new earthquake shook Mexico on Saturday, toppling already damaged homes and a highway bridge and causing new alarm in a country reeling from two even more powerful quakes this month that together have killed nearly 400 people.
The U.S. Geological Survey said the new, magnitude 6.1 temblor was centered about 11 miles (18 kilometers) south-southeast of Matias Romero in the state of Oaxaca, which was the region most battered by a magnitude 8.1 quake on Sept. 7.
It was among thousands of aftershocks recorded in the wake of that earlier quake, which was the most powerful to hit Mexico in 32 years and killed at least 90 people.
There was some damage in Oaxaca but no immediate reports of new deaths. The Federal Police agency posted images online showing a collapsed bridge that it said had already been closed due to damage after the Sept. 7 quake.
