Image source, EPAGermany's leader Angela Merkel has given a press conference following a cabinet meeting with the country's foreign minister and interior minister.
She said the Taliban had taken over Afghanistan with "breath-taking speed" and that this was a "bitter, dramatic and terrible development" particularly for the people of Afghanistan.
Merkel said that people should never forget those who lost their lives during the mission, including the 59 German soldiers who died in Afghanistan.
She added that the evacuation effort was the most important thing right now and of the 2,500 people, including their families, who worked with German forces, 1,900 are already back in Germany. Others are thought to be in a third country.
There are a further 1,000 people who worked with German development agencies and NGOs who also need to be brought to safety, she said.
Merkel said German military aircraft are on their way to Kabul but the situation there is still difficult.
Image source, Getty ImagesPlanes sent to help evacuate people from Afghanistan are having to be diverted to other cities because of the upheaval at Kabul airport.
Images from the Hamid Karzai International Airport show scenes of desperation and anguish, with people crowding the runways and standing on top of aircraft. Footage showed desperate Afghans trying to hang onto planes as they attempted to take off.
Two Czech military planes were diverted to Baku, Azerbaijan and a German evacuation plane was forced to change course and land in Uzbekistan.
The aircraft had been sent to help evacuate Czech and German nationals and Afghan colleagues from the country.
All flights - military and civilian - coming in and out of the airport were suspended as of Monday evening because of the chaos, the Afghan Civil Aviation Authority said on Monday.
The aviation authority said the country's airspace had been "released to the military" and advised commercial airlines to divert flights to avoid the airspace.

The world through its media
Image source, Shamshad TVAfghanistan’s main TV channels are still broadcasting, but with some noticeable differences - including the disappearance of all female presenters from the screen.
There has been a large increase in favourable comments on the Taliban on channels such as the state-run National Afghanistan TV and privately owned Tolo News, Ariana, Shamshad and 1TV.
Little criticism of the group has been seen so far on any of them. All have refrained from airing any music or soap operas.
Tolo News and 1TV have mostly been repeating programmes aired yesterday, possibly because of difficulties with their work.
However, Saad Mohseni, owner of the Moby Group - which includes Tolo TV and Tolo News TV - said in a tweet: “I can assure you our folks are OK and that we have continued with our broadcasting uninterrupted throughout this ‘transition’”.
Moby Group is Afghanistan’s biggest generator of entertainment and news and current affair programmes.
State TV, which was taken over by the Taliban on the evening of 15 August, has largely been airing religious programmes.
Shamshad TV, owned by a former presidential aide, has broadcast much pro-Taliban content. In one programme, the channel’s correspondent showed Kabul residents praising the group for bringing security and unity to the country.
Uzbekistan says about 750 Afghan military personnel have arrived in the country in the past 48 hours.
About 600 of those were aboard Afghan military aircraft, while a further 158 troops crossed into the country on Sunday.
Uzbekistan shares a narrow northern border with Afghanistan.
Uzbek authorities said they forced down 46 military aircraft in the southern city of Termez.
According to the Uzbek prosecutor-general's office, one Afghan aircraft and the Uzbek fighter jet that was escorting it collided. Both pilots ejected.
Video posted to social media showed an Afghan Black Hawk helicopter on the ground on what was said to be an Uzbek farm with about ten Afghan air force crew onboard.
The UK is to send 200 more troops to help in the evacuation of Kabul airport, the Ministry of Defence (MOD) has confirmed.
It says there will soon be 900 British military personnel on the ground.
A "small number" of RAF aircraft are also being diverted from other operations to assist, the MOD said.
It comes as the US announced it was expanding its number of troops by 1,000 to 7,000.
Image source, ReutersUS President Joe Biden has just arrived back in Washington DC, having cut short his trip to Camp David, the presidential retreat in Maryland.
He's set to make a speech in a few hours, at 20:45 BST / 15:45 EST, on the situation in Afghanistan.
The White House says he has been briefed by top national security officials on the state of affairs at Kabul's airport and the "ongoing efforts to safely evacuate American citizens, US Embassy personnel and local staff... and other vulnerable Afghans".

Image source, EPAStudents say they are scared of the Taliban rule
The BBC has been speaking to young people who are currently in Kabul.
One woman described the city as "silent". The Taliban are ruling the city and everyone is at home, she said.
"I had lots of plans for my future but now I can't go to work or university," she added.
"I don't know what our future is like. This has made me lose hope. I want to transfer my semester out of Afghanistan to continue my life normally.
"I'm just seeking for a way to get out of Afghanistan because there is no hope for women and the future."
Another resident said they were terrified to go out onto the street.
"We are emotionally, psychologically in a very bad condition. We are hopeless, it is like a countdown - waiting for our turn - to be captured by them," he said.
"Everyone in here is trying to escape to another country to escape execution".
We've been reporting about the chaotic scenes at Kabul airport today, with hundreds of Afghans trying desperately to escape their country after the Taliban takeover.
A company that provides up-to-date, high resolution satellite images - Maxar Technologies - has shared pictures on Twitter that appear to show queues of cars approaching the airport and large crowds of people on the airport runways.

Pentagon spokesman John Kirby also said he was confident that the US could move "thousands" of people out of the Afghan capital once the US had regained control of the airport.
"Capacity is not going to be a problem," he said at the press conference.
Kirby acknowledged he was concerned by how quickly the Taliban had moved, but said "no outcome has to be inevitable" in Afghanistan.
More now on that press conference by the US Department of Defense.
The Pentagon is focused on assisting the US state department, he said, which is working to evacuate US citizens and Afghan nationals.
Those nationals are seeking the Special Immigrant Visa - which is designed specifically for those who worked alongside American troops.
Image source, PA WireThe athletes won't be able to attend due to the unrest
Afghanistan was set to send two athletes to the Paralympic Games in Tokyo, but unrest in the country means they won't be able to attend.
The Afghanistan Paralympic Committee's Chef de Mission Arian Sadiqi, who is based in London, told Reuters news agency: "Unfortunately due to the current upheaval going on in Afghanistan, the team could not leave Kabul in time."
Zakia Khudadadi, who was set to be the first woman to represent the country at a Paralympic Games, had been due to arrive in Tokyo with track athlete Hossain Rasouli on 17 August.
Sadiqi said the team had tried to secure flights, but prices began to rise as the Taliban gained control of numerous cities.
"They [athletes] were really excited prior to the situation. They were training wherever they could, in their parks and back gardens," he said.
BBC Radio 5 Live
An Afghan woman living in the UK spoke to her niece, who lives in Kabul, on BBC Radio 5 Live earlier today and pleaded with her to stay safe.
Wahida told Sara (not her real name) to "stay inside, don’t move and don’t open the door".
Sara urged her aunt not to panic.
“Please don’t worry, let’s see what happens," she said.
Both women were speaking live to Patrick Kielty. Sara can’t escape Kabul as the embassies have all closed.
“The Taliban are in Kabul, they’re in control, the only thing we can do is not get hurt,” she said.
More now from that Pentagon briefing:
US troops are still "working to re-establish security" after breaches on the civilian side of the Kabul airport, said Pentagon spokesman John Kirby.
There are currently 2,500 American troops at the airport, with an additional 500 arriving in the coming hours, Kirby said.
"We anticipate that in the coming hours we'll be able to restore air operations at the airport," Kirby said. As of now, all flights in and out of Kabul have been halted.
The goal is to evacuate thousands of people per day, Kirby said, once flights are resumed.
Image source, ReutersThe Taliban must exercise restraint in order to protect lives, says the UN Secretary General.
Addressing the UN Security Council, Antonio Guterres said he had heard "chilling reports of severe restrictions on human rights throughout the country".
"I am particularly concerned by accounts of mounting human rights violations against the women and girls of Afghanistan," he says.
"We cannot and must not abandon the people of Afghanistan."
He called on the council to use "all tools at its disposal" to suppress the global terrorist threat in Afghanistan and ensure human rights are protected, and said all countries should be willing to take in Afghan refugees.
Guterres added that the UN still had staff and offices in areas now controlled by the Taliban, and that it would continue its presence while adapting to the security situation.
All military and civilian flights in and out of Kabul airport have been halted, a Pentagon spokesman has said.
It is unclear when they will resume, he added. US troops are currently working to secure the airport.
US action resulted in the deaths of two armed individuals, the Pentagon said.
Afghanistan: Former US interpreter speaks amid gunfire-hit evacuation from Kabul airport
A former US interpreter spoke to Newshour about trying to get out of Afghanistan from Kabul airport as the Taliban take over the city.
With sounds of gunfire in the background, he explained the problems he faced getting into the airport and the situation inside.
The situation at Kabul international airport is "tenuous", and US officials are considering evacuating all Americans and leaving Afghans behind, according to CBS News, the BBC's US partner.
The decision to abandon Afghan allies has not yet been made, said CBS National Security Correspondent David Martin, but it is "on the table" and will be explored if American troops cannot take control of the airport.
On Monday, US troops killed two armed Afghans who were part of the crowd overrunning the airport.
US President Joe Biden will return to the White House today to deliver remarks on the situation in Afghanistan.
He is scheduled to speak at 20:45 BST / 15:45 EST.
