The United States has completed its withdrawal from Kandahar Airfield in southern Afghanistan, once the second largest military base in the country for US forces, officials said on Friday.
Kandahar province was the birthplace of the Taliban and has in recent months seen intense clashes between the resurgent militants and Afghan forces.
US airstrikes were launched from the base just last week to help Afghan forces push back a major Taliban offensive.
"They have not officially handed over the base to us but I can confirm they left the base on Wednesday," said Khoja Yaya Alawi, a spokesperson for the Afghan army in Kandahar.
"They have handed over all the facilities to Afghan forces," added Massoud Pashtun, the director of Kandahar Airport.
An official handover is expected to take place after the Muslim holiday of Eid, which ends on Saturday, they said.
An Afghan army officer at Kandahar Airfield, who asked not to be named, told AFP that government forces would be left exposed by the pullout.
"It is now going to be very difficult for us to conduct operations," he said. "Our aircraft can't fly at night so the night operations are going to be difficult."
At its height, the airfield was the second largest base for US and international troops and the first airfield where US forces were stationed after the fall of the Taliban in 2001.
It was also the centre of the biggest drone operation by US special forces in Afghanistan.
The military has for years been steadily decreasing its presence there, accelerated after Washington struck a deal with the Taliban last year to completely withdraw from Afghanistan in return for security guarantees.
However, the US missed the May 1 deadline, extending it to September 11 — a move which angered the Taliban.
Although fighting between the US forces and the Taliban has stopped since the landmark agreement last year, battles rage daily between Afghan government forces and the militants, and have intensified since the missed deadline.
The Pentagon on Tuesday said it had so far completed between six and 12% of its final withdrawal.
The following day, the Afghan defence ministry announced that it had taken control of Camp Morehead, a US base in Kabul where American troops trained the Afghan military.
The camp will now be used by Afghan special forces.
