The last dedicated evacuation flight back to the UK left Kabul overnight, Sky News understands.
Remaining flights over the weekend are set to bring home British troops as well as the final small numbers of Afghan evacuees who have permission to fly, defence sources said.
The UK ambassador in Kabul, Laurie Bristow, said in a video posted on social media that his team had been “working until the very last moment”.
Almost 15,000 people have been airlifted to safety, he added, tweeting that “our commitment to the people of Afghanistan will endure”.
NATO’s senior civilian representative in Afghanistan, Stefano Pontecorvo, said the evacuation teams at Kabul’s airport had done as much as they could under the circumstances.
“We have a clean conscience,” he said.
