The United States will withdraw all its troops from Afghanistan by the 20th anniversary of the September 11 attacks, media reports show.

Quoting an unnamed person familiar with the matter, a report by the Washington Post said President Joe Biden will on Wednesday announce his decision to pull the troops out of the Middle Eastern country over the coming months.

Donald Trump's administration had previously set a May 1 deadline for the withdrawal in negotiations with the Taliban.

"This is the immediate, practical reality that our policy review discovered," Washington Post quotes the unnamed source.

"If we break the May 1st deadline negotiated by the previous administration with no clear plan to exit, we will be back at war with the Taliban, and that was not something President Biden believed was in the national interest."

The September 11, 2001 attacks were staged by members of terror group al-Qaeda, who hijacked four airplanes and crashed three of them into New York and Washington, leaving nearly 3,000 people dead and others missing.

Refusing to hand over Osama Bin Laden, the head of al-Qaida, who was quickly identified as the man responsible, the U.S. invaded Afghanistan, marking the start of Afghanistan war against the Taliban.

About 2,400 U.S. service members have been killed in the Afghan conflict and many thousands more wounded.
