The Taliban have ordered their fighters to enter parts of Kabul to prevent looting, their spokesman Zabihullah Mujahid has said, according to Afghan TV network Tolo. The BBC has not independently confirmed his statement.
Because security forces had left parts of the city and their checkpoints, Taliban forces were going in to prevent chaos and looting, he added.
In the statement, the Taliban called on the people not to be afraid of their militants.
-Taliban militants free inmates from Kabul jail
Footage posted online by a pro-Taliban news agency appears to show inmates being freed from the Pul-e-Charkhi prison in Kabul - the largest prison in Afghanistan.
Earlier on Sunday, Taliban forces overran the military prison at the former Bagram US air base.
Taliban and extremist fighters, including those belonging to the Islamic State, were among the 5,000 inmates being held at the Bagram prison.
-President Ghani leaves Afghanistan
President Ashraf Ghani has left the country, reports say, quoting Afghan officials.
It comes as Taliban reached the outskirts of Kabul.
Vice-president Amrullah Saleh is also reported to have fled.
Mr Ghani has come under increasing pressure to resign as major cities around Afghanistan have fallen to Taliban militants over the course of 10 days.
-I saved American lives but the US has turned its back on me
Omar* is in Kabul with his wife and children. He worked as a wartime interpreter for US and allied forces for five years - but now, he says, the US "has turned its back" on him.
"The president of the United States said, 'As you stood with us, we will stand with you'. So right now, where are they?"
Omar applied for a US visa in 2016, but was rejected for what the US embassy called a "lack of faithful and valuable service".
Now, Omar believes the Taliban's punishment will be worse for translators, despite a spokesman saying there will be "no revenge".
"There's no mercy for the linguists," he says. "The Taliban has said before, interpreters were the eyes and ears of the Americans - so the punishment will be different for us.
"As an interpreter I saved many American lives. So, they've really left me behind. Now I'm about to be killed, as is my family."
-Frenzied evacuation of US embassy
Helicopters have been seen landing and taking off from the US embassy in Kabul, as the evacuation of US personnel from Afghanistan gains speed.
As the Black Hawk and Chinook helicopters depart towards Kabul's international airport, some of them are dropping flares to deter Taliban rocket attacks.
According to NBC News reporter Richard Engel, the embassy will close as soon as all US personnel are transferred out, following intense negotiations with the Taliban for safe passage.
On Friday, embassy staff received the order to begin destroying sensitive documents, as well as items "which could be misused in propaganda efforts,” US media reported.
A core group of US diplomats who will are expected to remain in the country after the withdrawal will remain at the airport for an unspecified amount of time, a US official told the New York Times.
