A strong earthquake has struck central Mexico, killing more than 200 people and toppling dozens of buildings in the capital, Mexico City.
President Enrique Peña Nieto said more than 20 children had died and 30 were missing after a school collapsed.
The 7.1 magnitude quake also caused major damage in neighbouring states.
The tremor struck shortly after many people had taken part in an earthquake drill, exactly 32 years after a quake killed thousands in Mexico City.
The country is prone to earthquakes and earlier this month an 8.1 magnitude tremor in the south left at least 90 dead.
Emergency workers, aided by volunteers, are working through the night to search the rubble of collapsed buildings for trapped people.
Mexico’s Secretariat of Public Education (SEP) reported that at least 209 schools had been affected by the quake, 15 of which have suffered severe damage.
