US President Joe Biden is set to announce the withdrawal of all US troops from Afghanistan by September 11, an official told reporters on condition of anonymity, writes DW.

The symbolic date, 20 years to the day of the historic terrorist attack on the World Trade Center in New York, will end the longest war in the US history.

The Trump administration had set the pullout date for May 1. Biden’s decision will delay the end of the war by another five months.

The military alliance has 9,600 personnel in the country, of which some 2,500 are US troops.
