KABUL - The Taliban are “looking into” a video circulating on social media that appears to show its fighters executing captured members of an Afghan insurgent group, a government spokesman said Wednesday.

The National Resistance Front (NRF), a nascent group operating mainly out of the Panjshir Valley, said the video showed some of its fighters being executed, and accused the Taliban of “war crimes”.

The video, being shared widely on social media, shows two groups of men squatting on a hillside with their hands tied behind their backs before being shot with automatic rifles by Taliban fighters. The fighters can be heard shouting “Allahu Akbar”, and a man is later heard saying “stop it, stop it” after the captives slump forward, apparently dead.

Checks by AFP’s digital verification team show the first versions of the video only appeared online in the last 24 hours, and government spokesman Bilal Karimi said authorities were investigating. “We are looking into it to know exactly when these videos were filmed and to know whether they are old,” Karimi told AFP.

“But so far, we absolutely don’t know about the place, timing of the videos, or who the people in them are.” The footage went viral a day after the Taliban said its forces had killed at least 40 NRF fighters in clashes in the Panjshir Valley. The NRF said those shown being executed in the video were captured during fighting in the valley.

“The criminal Taliban... committed a war crime again by shooting & martyring eight” members of the NRF, the insurgent group’s spokesman Sibghatullah Ahmadi said on Twitter. The United Nations Assistance Mission in Afghanistan (UNAMA) said it was “gravely concerned” by the allegations.

“Parties have clear international obligations, including respect for detainees’ rights,” UNAMA said on Twitter, calling for action against those responsible. In July, UNAMA accused the Taliban of carrying out hundreds of human rights violations, including extra-judicial killings and torture, since they seized power. Many of the victims were former government officials and national security force members, the mission said, an accusation denied by the Taliban.

The scenic Panjshir Valley is famed for being the centre of Afghan resistance to the Soviet occupation of the 1980s and the Taliban’s first stint in power in the late 1990s. It was the last part of Afghanistan to hold out against the Taliban when they returned to power in August last year.
