U.S. still working to contact most of the estimated 1,500 American citizens left in Afghanistan
- Secretary of State Antony Blinken said the number of remaining U.S. citizens in Afghanistan is "difficult to pin down with absolute precision at any given moment" because the U.S. does not track the travel of Americans.
- Blinken's press conference Wednesday, his first since the collapse of the Afghan government to the Taliban more than a week ago, comes as U.S. and coalition forces intensify emergency evacuation flights.
WASHINGTON — Secretary of State Antony Blinken said Wednesday that there may be as many as 1,500 Americans in Afghanistan left to evacuate, a calculation that he described as "difficult to pin down with absolute precision at any given moment."
Blinken said during a press conference that the U.S. currently is "aggressively reaching out" to about 1,000 contacts "multiple times a day, through multiple channels of communication" to determine if they still want to leave and to give them instructions on how to do so. However, the ultimate number might be lower, Blinken said.
Blinken added that the State Department has been in direct contact with 500 other Americans in the last 24 hours with instructions on how to safely travel to the airport for evacuation.
"The U.S. government does not track Americans' movements when they travel around the world," Blinken explained. "There could be other Americans in Afghanistan who never enrolled with the embassy, who ignored public evacuation notices and have not yet identified themselves."
"We've also found that many people who contact us and identify themselves as American citizens, including by filling out and submitting repatriation assistance forms, are not, in fact, U.S. citizens, something that can take some time to verify. And some Americans may choose to stay in Afghanistan," the nation's top diplomat said.
The U.S. Embassy in Afghanistan early on Thursday issued a security alert on its website urging Americans to avoid traveling to Kabul airport and warned some at certain gates to "leave immediately."
"U.S. citizens who are at the Abbey Gate, East Gate, or North Gate now should leave immediately." the alert said.
A State Department spokesperson called it a "dynamic and volatile security environment."
White House press secretary Jen Psaki said Wednesday that many of the 1,000 contacts the U.S. is trying to reach are dual citizens who may not want to leave the country.
"Maybe they have extended family there, maybe they've spent their entire lives in Afghanistan and they're not yet ready to depart," Psaki told reporters during a press briefing. "Maybe they're working on a range of projects there and aren't yet ready to leave them. I know that's hard for us to understand as we're looking at the images, but for many of these Afghans, this is their home."
Blinken's press conference, his first since the collapse of the Afghan government to the Taliban more than a week ago, comes as U.S. and coalition forces intensify emergency evacuation flights.
In the past 24 hours, Western forces evacuated 19,000 people out of Kabul on 90 military cargo aircraft flights, a cadence of one departure flight every 39 minutes, according to the Pentagon.
Since the mass evacuations began Aug. 14, approximately 82,300 people have been airlifted out of Afghanistan. About 87,900 people have been evacuated since the end of July, including about 4,500 U.S. citizens and their families.
The Pentagon said Wednesday that 10,000 people are currently at Hamid Karzai International Airport in Kabul awaiting a flight. About 5,400 U.S. servicemembers are assisting with evacuation efforts, with nearly 200 U.S. military aircraft dedicated to the mission.
President Joe Biden on Tuesday reiterated to leaders of the G-7, NATO, United Nations and European Union that the United States will withdraw its military from Afghanistan by the end of the month.
The president warned that staying longer in Afghanistan carries serious risks for foreign troops and civilians. Biden said that ISIS-K, an Afghanistan-based affiliate of the terror group, presents a growing threat to the airport.
"Every day we're on the ground is another day we know that ISIS-K is seeking to target the airport and attack both U.S. and allied forces and innocent civilians," he said.
The Taliban said earlier Tuesday that the group will no longer allow Afghan nationals to leave the country on evacuation flights nor will they accept an extension of the withdrawal deadline beyond the end of the month.
"We are not in favor of allowing Afghans to leave," Taliban spokesman Zabihullah Mujahid told reporters during a press conference on Tuesday.
"They [the Americans] have the opportunity, they have all the resources, they can take all the people that belong to them, but we are not going to allow Afghans to leave and we will not extend the deadline," he said. Evacuations carried out by foreign forces after Aug. 31 would be a "violation" of a Biden administration promise to end the U.S. military's mission in the country, Mujahid said.
Clarification: There may be as many as 1,500 Americans still in Afghanistan awaiting evacuation. The State Department has given 500 of them specific instructions on how to reach Hamid Karzai International Airport safely. The U.S. is still trying to contact the remaining 1,000, though the number who actually want to leave may be lower, according to the State Department.
