A 6.1 magnitude earthquake shook southern Mexico on Saturday morning ( September 23, 2017), the US Geological Survey said, rattling a country still coming to grips with the devastation from two stronger temblors earlier this month.

Saturday's quake was centered in Oaxaca state, about 275 miles southeast of Mexico City.
