At least 134 people died when a powerful earthquake of magnitude 7.1 struck central Mexico on Tuesday, toppling buildings in the heavily populated capital where rescuers searched rubble frantically for survivors.
Thousands ran into the streets in panic, and millions lost electricity when the quake struck around lunchtime.
Mexico City Mayor Miguel Angel Mancera said 44 buildings were severely damaged or destroyed. Several major gas leaks and fires occurred.
Interior Secretary Miguel Angel Osorio Chong told local television that rescue teams were working painstakingly with picks and shovels.
“We have some buildings where we have reports that there could be people inside. They are doing it with lots of caution,” he said, adding that more rescue personnel would be needed.
