Thirty students killed Friday in a car bomb attack in eastern Afghanistan, officials said.
The explosion occurred near a hotel where students are report to be staying at the Elm Bridge, the capital of Logar province.
Eyewitnesses described the roofs collapsing and the victims trapped under the rubble.
It was not immediately clear who was behind the explosion.
Violence in Afghanistan has increased since U.S. President Joe Yaman announced the withdrawal of U.S. troops by 9/11.
The bomb exploded around 7 p.m. local .m (15:30 GMT) and destroyed buildings, including a local civilian hotel, according to local media reports.
Hasibullah Stanekzai, chairperson of logar provincial council, said some of the victims are staying in hotels, including high school students taking college entrance exams in the city.
Interior Ministry representative Tariq said up to 90 people injured in the blast.
The explosion caused major damage to the area, including hospitals and homes, he said.
“The roof of the house collapsed and people were trapped under the rubble,” he said.
“Security forces are trying to rescue the trapped people.
A video circulating online showed a victim being dragged from under the rubble. It seems that the ward of a nearby hospital was damaged by the explosion.
A representative for the governor of Logar province, Didar told Reuter’s news agency that the car exploded near the former provincial council president’s home, not far from the hospital.
The British Embassy in Kabul condemned the attack, saying that “this senseless violence against civilians must stop.”
The blast came a day after the U.S. military officially began withdrawing the remaining troops from Afghanistan.
President Joe Yaman announced earlier this month that all U.S. troops would leave Afghanistan before the 20th anniversary of the September 11, 2001 attacks.
