Eleven people were killed and 25 others injured Friday when a bus ran off the road and fell more than 100 meters (328 feet) in the northwestern Mexican state of Durango, authorities said.

The crash occurred at a spot known as The Devil's Spine on the highway linking Durango city with the Pacific resort of Mazatlan, the mayor of that municipality, Alejandro Higuera Osuna, told the media.

The Red Cross and the military joined fire rescue personnel at the site of the accident. The injured were taken to several different hospitals in Durango state.

Mexico averages around 24,000 traffic fatalities a year.

Sixteen people were killed and four others injured Aug. 6 in a collision between a van and a tractor-trailer in the northern state of Sonora, while an April 20 bus-truck crash in the Gulf coast state of Veracruz left 43 people dead and 27 injured. EFE
