A report by the RHIPTO Norwegian Center for Global Analyses says the Taliban have begun rounding up Afghans on a blacklist of people they believe have worked in key roles with the previous Afghan administration or with U.S.-led forces that supported it.

Citing the report, media reports say the Taliban have been conducting "targeted door-to-door visits" to find people on the list..

Deutsche Welle (DW) notes that it contradicts the less extreme image that the group has been trying to portray.

The report comes as the Taliban attempt to present a more moderate image of the group since seizing Afghanistan's capital on August 15.  They have pledged full amnesty for all who worked with the Western-backed, elected Afghan government.

According to Deutsche Welle, the RHIPTO Norwegian Center for Global Analyses report said the Taliban is “intensifying the hunt-down of all individuals and collaborators with the former regime.”

It said if they are not successful, the group is targeting and arresting family members and punishing them according to Shariah law.

According to the report, people in central positions in the Afghan military,  police and investigative units were particularly at risk.

Christian Nellemann, the intelligence group's executive director, told AFP that he expects those on the Taliban blacklist to face torture and execution if found.

Deutsche Welle says the non-profit group, which makes independent intelligence assessments, said the Afghanistan report was shared with agencies and individuals working within the United Nations.

But a UN official told Reuters: "This is not a report produced by the United Nations, but rather by the Norwegian Center for Global Analyses."
