'We have about 300 American citizens left who have indicated to us that they want to leave,' the secretary of State told ABC's This Week host Martha Raddatz. 'We are very actively working to help them get to the airport, get on a plane, and get out of Afghanistan.'
The Pentagon stated that it already began withdrawing troops from Afghanistan after 13 U.S. service members were murdered in a suicide bombing outside the Kabul airport on Thursday.
Almost 115,000 people have already been evacuated from Afghanistan, including Americans and Afghan allies. And since the end of July, 120,000 people have been relocated, the White House stated on Sunday.
White House Press Secretary Jen Psaki announced on Friday the administration cannot 'guarantee' everyone will get out.
On Sunday, the White House revealed that from 3:00 a.m. on Saturday to the same time Sunday, 2,900 people were evacuated from the Hamid Karzai International Airport in Kabul.
Blinken further told ABC that another attack on the Kabul airport is 'highly likely'.
'This is very high risk,' he stated. 'There is a high likelihood of additional attacks.'
'This is the most dangerous time in an already extraordinarily dangerous mission,' Blinken continued.
The head of the State Department didn't doubt that the president was to blame for their deaths.
'There are no words that I can say that, I think, anyone can say to assuage the grief that a parent is feeling at the loss of their child. Nothing,' he told NBC's Meet the Press host Chuck Todd in a different interview on Sunday morning.
'And if I were in his shoes, probably I'd feel exactly the same way,' Blinken continued.
He is referencing Steve Nikoui, the father of deceased Marine Lance Corporal Kareem Nikoui, who stated: 'Biden turned his back on [my son].'
Blinken replied to that grief by saying: 'All I can do is take responsibility for my own actions and do everything possible to continue to bring people out of Afghanistan who want to leave between now and the 31st, and every single day thereafter. That's my responsibility.'
'But I, as a parent myself, I feel deeply what he expressed,' Blinken said. 'And all I can say is, I'm deeply, deeply sorry.'
