Biden to call for end to ‘America’s longest war’

The US will continue to support Afghanistan after withdrawing all US troops, but not "militarily," President Joe Biden, has confirmed.

"It is time to end America's longest war," he will say in a speech later on Wednesday, according to preview excerpts released by the White House.

The pull-out is to coincide with the 20th anniversary of the 11 September 2001 terror attacks, officials say.

Some 2,500 US troops are part of the 9,600-strong Nato Afghan mission.
