According to a UN study seen by Reuters, the Taliban and its supporters are thought to have executed dozens of former Afghan officials, security force personnel, and civilians who worked with the foreign military contingent after the US-led withdrawal.

Despite the conclusion of battle with the Taliban’s takeover in August, UN Secretary General Antonio Guterres’ report to the UN Security Council presents a picture of worsening living circumstances for Afghanistan’s 39 million inhabitants.

“An whole intricate social and economic structure is collapsing,” Guterres explained.

The study is the latest in a series of warnings published by the UN Secretary-General in recent months about the humanitarian and economic crises that escalated after the Taliban captured Kabul as the last US-led foreign soldiers left and international donors cut critical financial aid.

Guterres proposed that the UN Security Council authorize a restructure of the UN mission to deal with the crisis, including the establishment of a new human rights monitoring section.

Despite the Taliban’s announcement of a general amnesty, the UN mission “continues to receive credible allegations of killings, enforced disappearances, and other violations” against former officials, security force members, and people who worked for the US-led international military contingent, according to the report.

According to the mission, more than 100 of those people have been slain since Aug. 15, with more than two-thirds of them purportedly killed by the Taliban or its affiliates.

According to the study, there are genuine claims of extrajudicial murders of at least 50 persons accused of membership to the local branch of the ISIS militant group.

“Human rights advocates and media workers continue to face intimidation, harassment, arbitrary detention, ill-treatment, and murders,” the report added.
