A powerful earthquake shook central Mexico on Tuesday, collapsing buildings in plumes of dust and killing at least 139 people. Thousands fled into the streets in panic, and many stayed to help rescue those trapped.
Dozens of buildings tumbled into mounds of rubble or were severely damaged in densely populated parts of Mexico City and nearby states. Mayor Miguel Angel Mancera said buildings fell at 44 places in the capital alone as high-rises across the city swayed sickeningly.
Hours after the magnitude 7.1 quake, rescue workers were still clawing through the wreckage of a primary school that partly collapsed in the city's south looking for any children who might be trapped. Some relatives said they had received Whatsapp message from two girls inside.
