Kabul Luftbruecke (Kabul Airlift) said that the plane, operated by Afghan airline Kam Air, flew from Kabul to Islamabad.

Among those on board were two Afghan air traffic controllers who had previously worked for the German armed forces, as well as “other local forces, vulnerable people from the human rights list and a German family,” a statement said.

Germany’s Foreign Office and Defence Ministry have not commented on the action.

Kabul Luftbruecke has accused the German government of dragging its feet in evacuating vulnerable people from Afghanistan following the radical-Islamist Taliban’s takeover in the troubled Asian country.

The German Defence Ministry recently classified 13 Afghan air traffic controllers on work contracts as local forces, meaning they will be offered protection in Germany.

This week, for the first time since the Bundeswehr airlift in August, the German government evacuated German nationals, former local staff and other Afghans in need of protection from Kabul by chartered plane.

A total of 329 people, including family members, were taken out of the country, the German Foreign Office announced on Twitter on Wednesday. They were initially taken to Qatar.
