Earthquake shakes Mexican capital

Workers evacuated buildings, fearful of stronger quakes

An earthquake has rocked central Mexico, prompting the evacuation of a number of buildings in the capital.

Hundreds of people are said to have run onto the streets of Mexico City as skyscrapers swayed. No injuries have been reported.

The quake was estimated to have a magnitude of 5.9 and was centred 200km (125 miles) south-west of the capital.

The Mexico City area is often hit by tremors. The last major earthquake, in 1985, killed thousands of people.
