According to a UN document, the Taliban are going door to door looking for anyone who worked with Nato forces or the former Afghan government.

Thousands of Afghans qualified for US evacuation were still to be flown out, many of whom were among the masses gathering around Kabul airport flashing their documents or proof they had worked on US military sites, as the 31 August deadline set by Biden for full US exit loomed. The British administration was likewise having difficulty evacuating its allies.

The organization has “priority lists” of persons it wants to arrest, according to the classified study, which was supplied by the UN’s threat-assessment experts and reviewed by a number of news outlets. It also threatens to kill or jail family members if the wanted do not surrender.

Since capturing control in a rapid attack, the hardline Islamist organization has attempted to reassure Afghans by promising “no revenge”

“Particularly at risk are individuals in central positions in military, police and investigative units,” the report said.

A German broadcaster said a family member of one of its reporters had been shot and killed by the Taliban when they came looking for the journalist, who had already fled the country.

“There are a high number of individuals that are currently being targeted by the Taliban and the threat is crystal clear,” Christian Nellemann, the report’s author, told the BBC.

“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.”

Mr. Nellemann cautioned that anyone on the Taliban’s blacklist may face mass killings.

Despite the Islamist group’s promise of a “general amnesty” for individuals across the nation after capturing Kabul by force on Sunday, the threat to anyone on the Taliban’s blacklist persists.

Meanwhile, a German non-governmental organization (NGO) said that it had shuttered its safehouses for Afghan nationals who collaborated with coalition forces, describing them as “death traps.”

“The Taliban are going door-to-door looking for local forces,” Marcus Grotian, the network’s commander, claimed. “This was foreseeable, and there has already been a visit to one of the safehouses by the Taliban. Thank God it was empty.”

During independence day festivities in Jalalabad, Taliban militants opened fire on civilians raising the Afghan flag, wounding a man and a teenage boy.

Al Jazeera’s Charlotte Bellis, reporting from Kabul, said: “There were some isolated protests linked to the flag in Kabul as well, with people, including women, walking down the streets past Taliban fighters waving the old flag and saying: ‘Our flag is our identity.’”

Foreign governments are still trying to get their citizens out of Afghanistan. Over 18,000 people have been evacuated from Kabul airport in the previous five days, according to a Nato officer.

Efforts to evacuate at-risk troops as quickly as possible are continuing, but Taliban checkpoints on the roads leading up to the airport are causing delays. Afghan citizens, in particular, are being turned back, despite the fact that individuals with US passports are typically permitted to cross.

Fears developed that a Taliban administration would be as cruel and murderous as the one that ruled Afghanistan earlier under a rigid and oppressive interpretation of Islamic sharia law. According to an Amnesty International investigation, Taliban forces cruelly tortured and “massacred” nine members of Afghanistan’s Hazara minority throughout their advance across the country.

Their triumph brings the group back to power 20 years after being deposed in a US-led invasion.
