At least 13 people, including three children, have now died following an earthquake on Saturday in Chechnya, near the war-torn capital city of Grozny, the Agence France-Presse is reporting. More than 100 were left injured.

The quake measured 6.3 on the Richter scale, and caused major damage to the country's infrastructure. It was centered some 25 miles (40 kilometers) east of Grozny. Citizens were scheduled to vote today (Sunday) in regional elections, so many were in temporary housing when the quake struck at about noon local time.
