An earthquake described by Mexico’s president as the country’s strongest in a century has struck off the southern coast, killing at least 16 people.
The quake, which President Enrique Peña Nieto said measured 8.2, struck in the Pacific, about 87km (54 miles) south-west of Pijijiapan.
A tsunami warning was issued for Mexico, with three-metre-high waves possible, and other nearby countries.
Severe damage has been reported in Oaxaca and Chiapas states.
The quake, which struck at 23:50 local time on Thursday (04:50 GMT Friday), was felt in Mexico City, with buildings swaying and people running into the street. The tremors there, about 1,000km from the epicentre, were reported to have lasted up to a minute.
President Peña Nieto said some 50 million Mexicans would have felt the tremor and that the death toll might rise.
