Thousands of Afghans are still desperate to leave and international governments are keen to get them out. It would all have been so much easier if NATO had held onto Bagram air base outside Kabul.
Now the Taliban have put up roadblocks to the city’s only airport making it hard for would-be travellers to enter. And then there’s logistics including the daunting task of processing so many people in such chaos and actually filling aircraft.
But the airport is only a small part of a much larger picture. Elsewhere in Afghanistan, there are reports of the Taliban conducting house to house searches, as many hide in fear from the new rulers.
