The video was uploaded on Wednesday (November 3), but the date the footage was shot could not be independently verified by Reuters. The Taliban's defense ministry spokesperson's Twitter account also shared the same video.
At least 25 people were killed and more than 50 wounded when gunmen attacked Afghanistan's biggest military hospital after two heavy explosions at the site in central Kabul, officials said.
Taliban soldiers are guarding the entrance to Afghanistan's biggest military hospital a day after the attack.
The blasts add to a growing list of attacks and killings since the Taliban completed their victory over the Western-backed government in August, undermining their claim to have restored security to Afghanistan after decades of war.
