Mexico City shaken by strong quake, death toll rises to 140

Nearly 140 people were killed when a powerful, 7.1-magnitude earthquake struck Mexico on Tuesday, toppling buildings in the capital and sowing panic on the anniversary of a devastating 1985 quake.

The quake sowed panic in the sprawling city of 20 million people, many of whom have memories of the quake 32 years ago that killed some 10,000 people in Mexico City.

Rescue crews and volunteers in Mexico City — home to 20 million people — clawed through the rubble of at least 49 collapsed buildings looking for survivors and bodies.

Local media reported that families were getting Whatsapp messages pleading for help from desperate relatives trapped under the debris.
