Scores of people have died as buildings across Mexico City collapsed under the force of an earthquake measuring magnitude 7.1.
At least 100 people have been killed across the country, with many more trapped inside buildings that caught fire after a powerful quake violently shook the capital.
Mexican TV and social media showed buildings collapsing and cars crushed by large chunks of fallen debris.
The magnitude 7.1 quake struck close to the town of Atencingo in the central state of Puebla, 123 km (76 miles) southeast of Mexico City, the U.S. Geological Survey said.
Other videos emerging on social media show a building explode after the quake hits, sending a giant orange fireball skyward.

It comes on the anniversary of a 1985 quake that did major damage to the capital Mexico City.
Thousands of people fled buildings across the capital as they were preparing drills for the deadly 1985 quake’s anniversary.
Earlier this month, Mexico was rocked by its most powerful earthquake in 32 years, which sparked panic and triggered a 2.3ft Tsunami.
Officials said the 8.1 magnitude earthquake killed at least 90 people and was the strongest quake to hit the capital since the 1985 tremor that killed thousands and flattened a large party of Mexico City.
