Chilling picture shows an Afghan police chief blindfolded and on his knees, moments before being executed by Taliban militants, according to reports.
The pictures circulated online appears to show General Haji Mullah Achakzai handcuffed while two men in the background have a discussion.
As the captive awaits his fate, a clicking sound appearing to be of a gun being loaded can be heard.
The commander for Badghis Province is thought to have been detained by the Taliban after they took over the area near the Turkmenistan border.
In just over a week, the Islamist militant group has managed to take over Afghanistan, and it is now said to be going door-to-doorhunting for collaborators for the ousted regime.
A version of the clip of General Achakzai, who is in his early 60s, was re-tweeted by former BBC Persia journalist Nasrin Nawa.
It first emerged on the feed of a group called @PanjshirProvince, which appears to be a resistance movement against the Taliban.
The clip shows General Achakzai being gunned down in a hail of gunfire before the camera pans over his dead body.
After a graphic content warning, Ms Nawa tweeted: ‘Haji Mullah, Police chief of Badghis province executed by #Taliban. This is their public amnesty!’
It comes after the Taliban insisted there would be ‘no revenge’ against former adversaries, as the group goes on the charm offensive to give itself an air of legitimacy.
Gen Achakzai, who was in his early 60s, was a staunch enemy of the Taliban and had fought against the group during the country’s decades long conflict.
The governor and police chief of Laghman Province, near Jalalabad, eastern Afghanistan have also been detained, according to reports, with Taliban high command to decide their fate.
