A United Nations document warns that the Taliban have been hunting for the People who worked with the NATO forces to the former Afghan Government from door to door.

The report goes against the recent Taliban promises of "no revenge." Taliban has repeatedly said it would not act out of revenge and does not want any domestic or foreign enemies.

However, the United Nations reported that the Taliban are targeting "collaborators." It was reported in a confidential document by the RHIPTO Norwegian Center for Global Analyses, which provides intelligence to the UN.

The head of the group behind the report, Christian Nellemann, said to the BBC that the threat is "crystal clear" as "there are a high number of individuals that are currently being targeted by the Taliban."

"It is in writing that, unless they give themselves in, the Taliban will arrest and prosecute, interrogate and punish family members on behalf of those individuals," he warned.

He also warned of a possible mass execution of the people who are on the blacklist of the group.
