Southern Mexico has been shaken by a 6.4 magnitude earthquake, causing power cuts and panic, but so far no reported injuries or damage. The US Geological Survey said the quake's epicentre was about 110km (70 miles) south-west from Tuxtla Gutierrez in the state of Chiapas. Residents there fled into the streets and have remained out of their homes in fear of possible aftershocks. The tremor was also felt in the capital, Mexico City.
The earthquake struck at 0650 local time (1250GMT) on Tuesday. "It was horrible. It really scared me," one resident of Tuxtla Gutierrez, Cecilia Gomez, told the Associated Press. The quake was also felt in the states of Oaxaca, Tabasco and Puebla.
In Mexico City, some 600km away, tall buildings swayed but no damage was reported.
