One eyewitness told Afghanistan International that families were eating when armed men took their phones. He said he had moved away from the scene and then heard gunfire and women screaming.
He added that ambulances arrived about two hours later and that a nearby Taliban vehicle did not immediately respond. According to him, Taliban forces arrived gradually after the attackers had fled.
“Everyone was killed. It was like Karbala, there were many bodies, and they were taken to a mosque,” he said.
The witness said he initially thought the attackers were Taliban morality police checking women.
Residents of Deh Mehri village said families had gathered for a picnic and pilgrimage.
Images and videos obtained by Afghanistan International show a scene marked by violence, with tents, clothing and shoes left behind.
Residents also shared footage showing a stream stained with blood.
Four gunmen reportedly opened fire on Shia civilians around 3pm on Friday in Deh Mehri.
Locals had gathered near a shrine, spending time together and sharing food when the attack occurred.
The Taliban said at least 11 people were killed and others injured, but eyewitnesses believe the toll is higher.
A Herat resident said in a video circulating online that a nearby stream had turned red with the victims’ blood, pointing to the area where the shooting took place.
No group has claimed responsibility, though ISIS-K has previously carried out attacks on Shia civilians in Herat and other parts of Afghanistan.
In another video, a local resident said the gunmen lined up civilians in the courtyard of a shrine before opening fire.
