7.1 Earthquake Rocks Mexico City, Central Mexico
A strong earthquake has struck central Mexico, toppling buildings in the capital Mexico City and killing several people, reports say.
The capital's airport has suspended operations after the 7.1 magnitude quake, and buildings across the city have been evacuated.
Fire has been reported in several buildings, with some people said to be trapped inside.
Earlier this month, a strong 8.1 magnitude tremor left at least 90 dead.
The epicentre of the quake was next to Atencingo in the central state of Puebla, some 120km (75 miles) from the capital Mexico City, the US Geological Survey said.
Damage was also reported in other towns around the capital, with local media reporting at least three deaths in Puebla.
The tremor happened as an earthquake drill was being held in Mexico City, on the 32nd anniversary of a quake that killed up to 10,000 people.
