Desperate rescue workers scrabbled through rubble in a floodlit search on Wednesday for dozens of children feared buried beneath a Mexico City school, one of hundreds of buildings wrecked by the countrys most lethal earthquake in a generation.
The magnitude 7.1 shock killed at least 225 people, nearly half of them in the capital, 32 years to the day after a devastating 1985 quake.
The head of Mexicos national civil defense agency, Luis Felipe Puente, posted a tweet saying 94 are known dead in Mexico City, 71 in Morelos state, 43 in Puebla, 12 in the State of Mexico, four in Guerrero and one in Oaxaca.
The disaster came as Mexico still reels from a powerful tremor that killed nearly 100 people in the south of the country less than two weeks ago.
Among the twisted concrete and steel ruin of the Enrique Rebsamen school, soldiers and firefighters found at least 22 dead children and four adults, while another 30 children and 12 adults were missing, President Enrique Pena Nieto said.
There were chaotic scenes at the school as bulldozers moved rubble under the buzz and glare of floodlights powered by generators, with parents clinging to hope their children had survived.
Mexicos civil defence agency has said the death toll has risen to 226 from Tuesdays magnitude 7.1 earthquake that knocked down dozens of buildings in Mexico City and nearby states.
Twenty-two bodies were pulled from rubble at a school in Mexico City, while rescuers searched for a further 38 missing people at the site.
The official Twitter feed of agency head Luis Felipe Puente said early Wednesday that 117 people were confirmed dead in Mexico City, and 55 died in Morelos state, which is just south of the capital.
