Rescuers are scrambling to find survivors after a massive earthquake hit Mexico City on Tuesday night, leveling buildings, trapping people under fallen debris and killing scores of people.

As of this publication, authorities had estimated that around 216 people had died in Mexico City (an early estimate put the number at 248. That number was later revised.) Soldiers, rescuers and civilians—including college students—all worked side by side to clear rubble and search for survivors.

According to CNN, the 7.1-magnitude earthquake was about 3 miles northeast of San Juan Raboso and 34.1 miles southwest of the city of Puebla. President Enrique Peña Nieto told reporters that 22 bodies had been pulled from an elementary school, and at least 30 children were still missing. An estimated five million are without power.

In a bit of bitter irony, the earthquake hit on the anniversary of a 1985 quake that killed thousands in Mexico City. In fact, just hours before the event, many residents of Mexico City were participating in commemorative earthquake preparation drills.

U.S. President Donald Trump tweeted that the U.S. would “be there” for the people of Mexico.
