The earthquake that struck Mexico City on September 19 has killed at least 230 people and caused major damages across central states.
In a national address in which he declared three days of mourning, President Enrique Pena Nieto said, "We are facing a new national emergency."
Dozens of buildings collapsed across the country, including a number of churches, killing worshippers inside.
And in Mexico City, 22 bodies were pulled from the rubble of a destroyed primary school.
Desperate searches for survivors in hotspot areas continue.
