Mexico City, Dhu-AlHijjah 18, 1438, Sep 9, 2017, SPA -- Mexico authorities on Friday said that 60 people had been killed across three states following an 8.2-magnitude earthquake that struck a day earlier in the waters off the country's south-west coast. According to dpa, forty-five of the deaths occurred in the state of Oaxaca, Luis Felipe Puente, the head of Mexico's national emergency services, said. Twelve were killed in Chiapas state, Governor Manuel Velasco said, while three deaths were recorded in Tabasco state. The quake - declared by President Enrique Pena Nieto to be the strongest to hit Mexico in nearly a century - struck at a depth of 58 kilometres under the Pacific Ocean at 11:49 pm Thursday (0449 GMT Friday), when many people had retired for the evening. Mexico has since suffered more than 260 aftershocks, Pena Nieto said. At least 200 people had been injured, and 1,800 soldiers had been dispatched to provide aid, he added. Some of the strongest aftershocks registered a magnitude of 6.1, with many over magnitude 5. Pena Nieto warned that some might reach a magnitude of 7. --SPA 15:31 LOCAL TIME 12:31 GMT www.spa.gov.sa/w483780
