The Pentagon continues to withdraw its units from Afghanistan as part of the announced reduction in the number of troops.
A convoy of American military equipment was spotted in Kandahar towards the border with Pakistan.
The Taliban on Thursday welcomed an announcement by President Donald Trump on pulling out U.S. troops by Christmas.
It was “a positive step towards the implementation of (the) Doha agreement,” a spokesman for the Islamist group, Mohammad Naeem, said in a statement.
Trump said on Twitter on Wednesday: “We should have the small remaining number of our BRAVE Men and Women serving in Afghanistan home by Christmas!”
The Doha agreement, signed between the U.S. and Taliban in February, drew up plans to pull out foreign forces from Afghanistan after two decades of war, in exchange for security guarantees from the insurgent group.
