The earthquake hit at 1:24 a.m. about 46 kilometers (28.5 miles) southwest of the city of Khost, which lies close to the country’s border with Pakistan, according to the United States Geological Survey (USGS).
The quake registered at a depth of 10 kilometers (6.2 miles), according to USGS, which assigned the quake a yellow alert level — indicating a relatively localized impact.
Casualties were reported in the Barmal, Zirok, Nika and Giyan districts of Paktika province, with more than 600 injured, according to Bakhtar.
Local officials and residents have warned that the death toll is likely to rise, according to Bakhar. Full casualty figures are not yet clear, and CNN is unable to independently confirm Bakhtar’s reporting.
Photos from Paktika province, just south of Khost province, show destroyed houses with only a wall or two still standing amid the rubble, and broken roof beams.
Najibullah Sadid, an Afghan water resources management expert, said the earthquake had coincided with heavy monsoon rain in the region — making traditional houses, many made of mud and other natural materials, particularly vulnerable to damage.
“The timing of the earthquake (in the) dark of night … and the shallow depth of 10 kilometers of its epicenter led to higher casualties,” he added.
A Taliban deputy spokesperson, Bilal Karimi, said the earthquake had been “severe,” and asked aid agencies to “urgently send teams” to the area affected.
In a tweet on Wednesday, the World Health Organization said its teams were on the ground for emergency response, including providing medicine, trauma services and conducting needs assessments.
Pakistan’s Prime Minister Shehbaz Sharif extended his condolences and an offer of support in a tweet on Wednesday. “Deeply grieved to learn about the earthquake in Afghanistan, resulting in the loss of innocent lives,” he wrote. “People in Pakistan share the grief and sorrow of their Afghan brethren. Relevant authorities are working to support Afghanistan in this time of need.”
