Mexico earthquake: Death toll rises as rescue effort begins
The number of people killed by a powerful earthquake off the southern coast of Mexico has risen to at least 58, officials say.
A huge rescue operation is under way in the worst-hit states of Tabasco, Oaxaca and Chiapas where people are feared trapped under rubble.
President Enrique Peña Nieto says at least 200 people have been injured.
The 8.1-magnitude quake was the strongest to hit the region in a century.
