August 15 marks the one-year anniversary since the fall of Kabul to the Taliban.

This clip shows hundreds of desperate Afghans left standing in sewage in a moat for hours outside Kabul airport on August 24 before being told they could not enter because they did not have visas in their passports.

Many of the fleeing locals were former Australian embassy guards and their families who said they were forced to stand for hours in the faeces-filled water despite assurances they would be able to fly out of the country.

Footage showed the men and their families desperately trying to show their documents to soldiers on a barrier wall above them.

Some of them told Australian media that they stood for hours in the sewage and found it very difficult to climb out.

Eventually, the group left the area fearing a possible Taliban attack, according to Australian media.
