'Time to bring our forces home' from Afghanistan: Blinken
US Secretary of State Antony Blinken (L) and the transatlantic alliance NATO's chief Jens Stoltenberg (R) hold a press conference.
US President Joe Biden is to announce formally later Wednesday that Washington will withdraw its remaining 2,500 troops from Afghanistan by September 11 -- 20 years after the attacks in the America that sparked its longest war.
NATO partners meeting in Brussels, some physically but most virtually, look set to agree to wrap up the alliance's 9,600-strong mission in Afghanistan at the same time as the group's major military power leaves.
"This is an important moment, for our alliance," Blinken said.
He insisted that, despite the pull-out, "our commitment to Afghanistan, to its future, will remain".
The draw down delays only by around five months an agreement with the Taliban by former US president Donald Trump to withdraw troops, amid a growing consensus in Washington that little more can be achieved.
The decision came as Turkey announced an international peace conference on Afghanistan in hopes of reaching an agreement that brings stability to a nation battered by nearly 40 years of war.
But the Taliban, newly emboldened, said they would boycott the conference.
