ISLAMABAD >> Two 6.3 magnitude earthquakes killed dozens of people in western Afghanistan on Saturday, the country’s national disaster authority said.

The United Nations gave a preliminary figure of 320 dead, but later said the figure still was being verified. Local authorities gave an estimate of 100 people killed and 500 injured, according to the same update from the U.N. Office for the Coordination of Humanitarian Affairs.

Mohammad Abdullah Jan said four villages in the Zenda Jan district in Herat province bore the brunt of the quakes and aftershocks. Dozens of houses have been damaged.

The United States Geological Survey reported the 6.3 magnitude temblors. It said the epicenter was 24.8 miles northwest of Herat city. There was an aftershock with a 5.5 magnitude.

A map on the USGS website indicates seven earthquakes in the area. At least five powerful earthquakes struck the city around noon, Herat city resident Abdul Shakor Samadi said.

“All people are out of their homes,” Samadi said. “Houses, offices and shops are all empty and there are fears of more earthquakes. My family and I were inside our home, I felt the quake.” His family began shouting and ran outside, afraid to return indoors.

The World Health Organization in Afghanistan said it dispatched 12 ambulance cars to Zenda Jan to evacuate casualties to hospitals.

Telephone connections went down in Herat, making it hard to get details from affected areas. Herat province borders Iran.
