There are no reports of casualties or significant damage, but frightened residents across the Mexican capital fled their homes as the tremor began.

The earthquake was felt in several southern and western Mexican states at 09:27 local time.

Windows were broken and trees fell in Chilpancingo, capital of Guerrero.

In Acapulco, where many tourists were enjoying the Easter holiday, there were scenes of panic.

Mexico lies on top of three continental plates and is regularly shaken by tremors.
