European nations and the EU scrambled to evacuate their citizens and local staff from Kabul on Sunday, as NATO said it would keep the airport open with the Taliban closing in on power.
The hardline Islamists were on the brink of total victory in Afghanistan, after the government conceded it was preparing for a "transfer of power".
NATO Secretary General Jens Stoltenberg said the alliance "was helping keep Kabul airport open to facilitate and coordinate evacuations" after consulting with member countries.
The European Union was left desperately trying to find a solution for its Afghan staff facing possible reprisals, and seeking to convince the 27 member states to offer them visas.
"The matter is extremely urgent, we take it very seriously and continue to work hard, together with EU member states, on implementing rapid solutions for them and ensuring their safety," an EU spokesman said.
Germany, France and the Netherlands were among countries moving diplomatic personnel from their embassy in Kabul to the airport ahead of evacuation.
"We are not going to risk our people falling into the hands of the Taliban," Foreign Minister Heiko Maas told the Bild daily.
Haas later announced that German embassy staff would start being flown out from Sunday.
A Bundeswehr aircraft will also depart Sunday night for the Afghan capital to help with the evacuation in coming days, Maas added.
The army will fly passengers to an unnamed "neighbouring country", where they will then be put on civilian flights bound for Germany, the minister said.
A core team of the embassy will carry on operating from the airport where they are currently sheltering, to help in particular with the evacuations.
"We are doing everything now to enable our nationals and our former local employees to leave the country in the coming days," Maas said.
But he warned the situation is "difficult to predict" and said Germany was working in close cooperation with allies.
Canada is temporarily closing its embassy in Kabul after evacuating staff ahead of Taliban fighters' arrival in the Afghan capital, said the foreign ministry in Ottawa.
Canadian personnel were already on their way back home, a statement said.
The ministry added that the embassy would reopen once conditions allowed a resumption of normal activities under adequate security.
France's ambassador to Afghanistan tweeted a video of himself leaving the Green Zone in Kabul aboard a helicopter as Paris looked to set up a temporary mission at the airport.
In Paris the foreign ministry said military reinforcements were being deployed to the United Arab Emirates to help with evacuations through Abu Dhabi.
Other NATO members including Britain, Italy, Denmark, Sweden and Spain have also announced they are evacuating their embassy personnel.
The French presidency said it would "do the utmost to guarantee the safety" of French nationals still in the country as well as Afghan staff.
In a statement it said the evacuation, involving several hundred people, had begun in April.
- 'Exceptional effort' -
Paris has vowed an "exceptional effort" to welcome Afghans under threat for their human rights work. More than 600 Afghans employed in French organisations in the country have already arrived in France along with their families, the government said Friday.
Britain was deploying around 600 troops to help evacuate its roughly 3,000 nationals from the country, and Prime Minister Boris Johnson said the "vast bulk" of remaining embassy staff in Kabul would return to the UK.
He was to hold fresh crisis talks on Wednesday, recalling parliament from the summer break to discuss what Britain, which lost 457 troops in the two-decade-long war, should do next.
Italy's defence ministry said a first military plane would arrive Sunday to begin "emergency evacuation" operations.
Denmark, Norway and Finland are temporarily shutting their Kabul embassies, ministers from the Nordic countries said on Friday.
Finland will offer asylum to 170 local staff and their families.
Swedish Foreign Minister Ann Linde also noted that the country's evacuees would include Afghan interpreters and other local staff.
Meanwhile the Dutch embassy in Kabul was evacuated overnight and was operating from a makeshift office near the airport, the country's foreign ministry said Sunday.
The Netherlands said Friday that it would take in Afghan interpreters and some other embassy staff.
Russia, for its part, said it does not plan to evacuate its embassy in Kabul.
Foreign ministry official Zamir Kabulov said Russia was among a number of countries to receive assurances from the Taliban that their embassies would be safe, according to the RIA Novosti agency.
