Afghanistan Disaster Management Authority’s spokesman Mullah Janan Saiq said the death toll could further rise, adding that the tremors caused heavy damage in northwestern Herat and Badghis provinces.

"Three villages in Herat province were completely destroyed, hundreds of people are still trapped under the debris," Saiq told Anadolu over the phone.

He added that it was difficult to find the exact number of casualties, but so far the figure of 1,000 was reported by local officials.

According to the US Geological Survey (USGS), strong earthquakes of magnitude 5.5, 5.9, and 6.2 jolted the Afghan provinces. It said the epicenter was 40 kilometers (24.8 miles) northwest of Herat city.

The World Health Organization's Afghanistan office said its teams were in hospitals assisting treatment of wounded and assessing additional needs.
