Mexico ? A strong 6.5-magnitude earthquake rocked the southern Mexican state of Chiapas on Thursday, shaking homes and prompting people to flee into the streets.

The quake was felt across the border in Guatemala and as far south as El Salvador. Mexican and Guatemalan emergency officials said there were no immediate reports of injuries or damage, although they were still investigating.

The quake struck at 1:41 p.m. about 13 miles from the city of Suchiate, on the Guatemalan border, according to the U.S. Geological Survey.
