American citizens have been told to leave Afghanistan immediately as the Taliban captured three cities in a sweeping offensive.
The US Embassy in Afghanistan put out an urgent security alert on Saturday telling its citizens to leave the country using available commercial flight options.
"Given the security conditions and reduced staffing, the embassy's ability to assist US citizens in Afghanistan is extremely limited even within Kabul," the alert stated.
US citizens were told to develop a plan of action that did not rely on US government assistance.
Taliban fighters tightened the noose around northern Afghanistan on Sunday, capturing three more provincial capitals after seizing much of the countryside in recent months.
The Taliban seized the commercial hub of Kunduz and then broke through in Sar-e-Pul and Taloqan.
The insurgents have snatched up five provincial capitals in Afghanistan since Friday in a lightning offensive that appears to have overwhelmed government forces.
They are now threatening major cities like Kandahar and Lashkar Gah in the south and Herat in the west.
Fighting in Afghanistan's long-running conflict has intensified since May, when foreign forces began the final stage of a withdrawal due to be completed later this month.
US President Joe Biden has asserted in recent weeks that the US withdrawal from the country would continue despite the Taliban's advances.
President Biden has been briefed on the situation in Kunduz, a White House official said.
"The President has been briefed and senior officials from the NSC, State, and DOD (Department of Defence) are actively engaging through secure channels with Embassy Kabul to assess developments," the official said.
Australia completed its formal troop withdrawal from Afghanistan in July.
We have confirmation that Kunduz and Sar-i-Pul provincial capitals have fallen to the Taliban. Govt forces control only an army base in Sar-i-Pul & the airport/army corps base in Kunduz. Clashes are going on in both cities.
In Kunduz, capital of the province of the same name, one resident described the city as being enveloped in "total chaos".
"After some fierce fighting, the mujahideen, with the grace of God, captured the capital of Kunduz," the Taliban said in a statement.
"The mujahideen also captured Sar-e-Pul city, the government buildings and all the installations there."
The insurgents said on Twitter later on Sunday that they had also taken Taloqan, the capital of Takhar province.
Parwina Azimi, a women's rights activist in Sar-e-Pul, told AFP by phone that government officials and the remaining forces had retreated to an army barracks about 3km from the city.
The Taliban had the compound "surrounded", said Mohammad Hussein Mujahidzada, a member of the provincial council.
Taloqan was the next to fall, with resident Zabihullah Hamidi telling AFP by phone that he saw security forces and officials leave the city in a convoy of vehicles.
"The city is unfortunately fully in Taliban hands," a security source told AFP.

A perennial target
Kunduz is the most significant Taliban gain since the May offensive began – it has been a perennial target for the insurgents, who briefly overran the city in 2015 and again in 2016 but never managed to hold it for long.
The defence ministry said government forces were fighting to retake key installations.
Spokesman Mirwais Stanikzai said reinforcements including special forces had been deployed to Sar-e-Pul and Sheberghan.
"These cities that the Taliban want to capture will soon become their graveyards," he said.
Kabul's ability to hold the north may prove crucial to the government's long-term survival.
Northern Afghanistan has long been considered an anti-Taliban stronghold that saw some of the stiffest resistance to militant rule in the 1990s.
The region remains home to several militias and is also a fertile recruiting ground for the country's armed forces.
"The capture of Kunduz is quite significant because it will free up a large number of Taliban forces who might then be mobilised in other parts of the north," said Ibraheem Thurial, a consultant for International Crisis Group.
Washington's former envoy to Kabul, Ryan Crocker, said a prolonged civil war is a more likely outcome than a swift Taliban takeover of the entire country.
"They're doing what they're doing in part to create a climate of fear and panic," Mr Crocker told US ABC's This Week.
Vivid footage of the fighting was posted on social media over the weekend, including what appeared to be large numbers of prisoners being freed from jails in captured cities.
The Taliban frequently targets prisons to release incarcerated fighters to replenish their ranks.
On Friday, the insurgents seized their first provincial capital, Zaranj in southwestern Nimroz on the border with Iran, and followed it up by taking Sheberghan in northern Jawzjan province the next day.
US air strikes
The pace of Taliban advances has caught government forces flat-footed, but they won some respite late on Saturday after US warplanes bombed Taliban positions in Sheberghan.
Sheberghan is the stronghold of notorious Afghan war lord Abdul Rashid Dostum, whose militiamen and government forces were reportedly retreating east to Mazar-i-Sharif in Balkh province.
Dostum has overseen one of the largest militias in the north and garnered a fearsome reputation fighting the Taliban in the 1990s – along with accusations his forces massacred thousands of insurgent prisoners of war.
A retreat of his fighters dents the government's recent hopes that militias could help the overstretched military.
Hundreds of thousands of Afghans have been displaced by the recent fighting, and on Saturday, 12 people were killed when their bus was struck by a roadside bomb as they tried to flee Gardez in Paktia province.
"I lost my mother, father, two brothers, two sisters-in-law and other members of the family," said Noor Jan.
The withdrawal of foreign forces is due to finish at the end of this month ahead of the 20th anniversary of the September 11 attacks. The US-led invasion sparked by 9/11 toppled the first Taliban regime in 2001.
