Miller added that the military will eventually hand over all their bases to Afghan forces, Sputnik reported.
"We have started withdrawing from a number of bases ... Even if Afghanistan has access to a peace agreement, we have been told to leave", Miller said at the press conference.
The announcement comes as NATO Secretary-General Jens Stoltenberg revealed the bloc's plans to start withdrawing troops from Afghanistan by 1 May. The alliance intends to complete the withdrawal within several months.
US President Joe Biden, in turn, vowed to withdraw US troops by 11 September, on the 20th anniversary of the 9/11 attacks.
Under the terms of the previous US-Taliban agreement, signed in Doha by then-President Donald Trump, the US withdrawal from Afghanistan, in exchange for the Taliban's commitment not to host terrorist forces in the country that could threaten US national security, was supposed to be effectuated on 1 May. However, new President Biden admitted that meeting the original deadline could be "tough".
Despite the launch of peace talks between the movement and Kabul in Qatar's Doha last September, clashes between the Taliban and the Afghan military still continue to rock the country.
