(CNN) – More than 900 people were killed and hundreds more wounded after a magnitude 5.9 earthquake hit eastern Afghanistan Wednesday, according to an official from the country’s disaster management authority.
It is the deadliest quake to hit the Asian nation in decades.
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.
The death toll stands at more than 900 and at least 600 people were injured in the quake, Deputy Minister for the State Ministry for Disaster Management Sharafuddin Muslem told a news conference Wednesday.
Most of the deaths were in Paktika province, in the districts of Giyan, Nika, Barmal and Zirok, according to the ministry.
In neighboring Khost province, 25 people were killed and several others were injured, and five people were killed in Nangarhar province, the disaster management authority said.
Photos from Paktika province, just south of Khost province, show houses turned to rubble 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 team of medics and seven helicopters have been sent to the area to transport injured people to nearby hospitals, Afghanistan’s Ministry of Defense said in a tweet on Wednesday.
The Taliban held an emergency meeting to organize providing transportation to the injured and material aid to the victims and their families, Taliban spokesperson Zabiullah Mujahid said.
Prime Minister Mohammad Hassan Akhund called the meeting at the country’s Presidential Palace to instruct all relevant agencies to send emergency relief teams to the affected area, Mujahid said in a tweet.
“Measures were also taken to provide cash assistance and treatment,” Mujahid said and added that agencies were “instructed to use air and land transport for the delivery of food, clothing, medicine and other necessities and for the transportation of the wounded.”
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.
