Daily US Times: Amnesty International said the Taliban murdered 13 ethnic Hazara people, including a teenage girl.
The prominent rights group said it found evidence the victims were massacred in Daykundi province in August.
Nine of them were former government soldiers who had surrendered to the Taliban, according to Amnesty, adding that the killings appeared to be a war crime.
The Taliban denied the allegation, saying the Amnesty report only showed “one side” of the story.
The Hazara community is the third largest ethnic group of Afghanistan.
They mainly practice Shia Islam and have faced long-term persecution and discrimination in predominantly Sunni Pakistan and Afghanistan.
This is the second time the Taliban have been accused of killing members of the Hazara community since the group took control of the country in August.
Amnesty International said that two other victims of the alleged killings in Daykundi province were civilians, including a 17-year-old girl reportedly shot when the Taliban opened fire on a crowd of soldiers’ families.
The civilians were killed as they attempted to flee, Amnesty’s report said, which was published on Tuesday.
Agnès Callamard, secretary-general of Amnesty International, said: “These cold-blooded executions are further proof that the Taliban are committing the same horrific abuses they were notorious for during their previous rule of Afghanistan
. The Taliban say they are not targeting former employees of the previous government, but these killings contradict such claims.”
A previous report from the rights group, released in August, said the Taliban had “massacred” nine members of the Hazara minority in Ghazni province in July.
