6.5-magnitude quake shakes Mexico City

President Claudia Sheinbaum was forced to evacuate the presidential palace during her regular morning press conference, along with the journalists in attendance, when the earthquake alert sounded.

Sheinbaum said the earthquake's epicenter was situated 15 kilometers (nine miles) from San Marcos, in the southern state of Guerrero. That is about 230 kilometers from Mexico City.

Sheinbaum said that preliminary reports indicated no serious damage in either Mexico City or Guerrero.
