(KABUL, Afghanistan) — Chaos has enveloped Kabul after Afghanistan’s government collapsed and the Taliban seized control, all but ending America’s 20-year campaign as it began: under Taliban rule.

Two suicide bombers affiliated with ISIS-K carried out what the Pentagon called a “complex attack” outside the Hamid Karzai International Airport in Kabul on Thursday, killing at least 13 American service members and wounding 18, among scores of Afghan casualties.

President Joe Biden has addressed the nation on the attack from the White House Thursday, saying, “America will not be intimidated.” Biden sat down with ABC News’ George Stephanopoulos for an exclusive one-on-one interview at the White House last week, the president’s first interview since the withdrawal from Afghanistan, and warned of the threat of attacks on the ground.

US, allies evacuate 12,500 people from Kabul in past 24 hours

The United States has evacuated and facilitated the evacuation of some 105,000 people from Kabul since Aug. 14, when the Taliban closed in on Afghanistan’s capital, according to a White House official.

In a 24-hour period from Thursday to Friday, 35 U.S. military flights carried approximately 8,500 evacuees out of Kabul. Another 4,000 people were evacuated via 54 coalition aircraft. Since the end of July, approximately 110,600 people have been relocated from Kabul via U.S. military and coalition flights, the White House

Philadelphia airport to receive Afghan refugees

People fleeing Afghanistan are expected to arrive at Philadelphia’s primary airport in the coming days, according to a city spokesperson.

“This is a federal-led operation, and we are collaborating with the federal government in this emergency response, protecting the rights and dignity of the Afghan families arriving in the country,” the spokesperson told ABC News on Friday. “We stand ready to provide medical assistance, housing, and connection to our diverse community of immigrant service providers who can assist with an array of social services.”

The Philadelphia International Airport is the second airport in the United States to welcome arrivals of Afghan refugees, in addition to the Dulles International Airport in Virginia.

It was unclear when or exactly how many Afghan refugees would be landing in Philadelphia.

“Philadelphia stands in solidarity with Afghan refugees and we look forward to providing them a safe haven in our Welcoming City,” Philadelphia Mayor Jim Kenney said in a statement.

UK enters final stages of Afghanistan evacuation

The United Kingdom announced Friday that it has entered the final stages of its evacuation from Afghanistan and no more people will be called to the airport to leave.

Processing facilities at the Baron Hotel in Kabul, outside the Hamid Karzai International Airport, have been closed and the British Armed Forces will now focus on evacuating the U.K. nationals and others who have already been processed and are at the airport awaiting departure, according to a press release from the U.K. Ministry of Defense.

“The U.K.’s ability to process further cases is now extremely reduced and additional numbers will be limited. No further people will be called forward to the airport for evacuation,” the defense ministry said. “Evacuating all those civilians we have already processed will free up the capacity needed on U.K. military aircraft to bring out our remaining diplomats and military personnel.”

U.K. Defense Secretary Ben Wallace called it a “remarkable achievement” that his government has evacuated more than 13,000 people from Kabul since Aug. 13, when the Taliban closed in on Afghanistan’s capital.

“Our top priority as we move through this process will be the protection of all those involved who are operating in a heightened threat environment,” Wallace said in a statement Friday. “It is with deep regret that not everyone has been able to be evacuated during this process.”

“We will continue to honour our debt to all those who have not yet been able to leave Afghanistan,” he added. “We will do all that we can to ensure they reach safety.”

(KABUL, Afghanistan) — When Waheed Arian heard of the two bombings out Kabul’s airport in Afghanistan, he rushed to call his family members to ensure that they were safe. Arian is a doctor and ex-refugee, who fled Afghanistan during the Taliban’s rule in 1999, and now lives in the United Kingdom.

With sweaty palms, a racing heart and the memories of death and destruction from his time in Afghanistan as a child, he’s wary of what the future might hold for him and his family.

“When I get off the phone, I break down in tears because I feel helpless,” Arian told ABC News. “This is the case for so many Afghans whose families are over there. … It haunts you forever.”

The bombings, for which the terrorist group ISIS-K has claimed responsibility, left at least 60 Afghan civilians dead, as well as at least 13 U.S. service members, according to the Pentagon.

The attack on Hamid Karzai International Airport, the main source of hope for those trying to escape the city and seek refuge elsewhere, has left many Afghans feeling desperate.

Waiting for news from home

Shabnam, who asked ABC News to use only her first name for the safety of her family in Afghanistan, said she can’t concentrate. The ex-refugee, who is now a citizen living in the U.S., said she is numb and can’t focus on her work, her schooling or her responsibilities as she awaits news about her family’s fate.

When Shabnam was asked if her family was safe, she responded: “What does that mean? If I say that they are safe, they’re safe as prisoners. … The banks are closed. The businesses are closed. Everything is closed, and they don’t have freedom of speech anymore.”

Shabnam is calling on international forces to step up and help the Afghan people before the country reverts back to its old ways, particularly calling on the U.S. to take the lead.

“It is their responsibility as our leaders, the responsibility of the international community not to just not watch and be silent,” Shabnam said.

Uncertainty plagues Afghan families

With the Taliban taking over Afghanistan before the United States’ Aug. 31 deadline to withdraw troops, many citizens fear what could come of their country and their livelihood in the Middle Eastern nation.

Activist and Afghan journalist Mahbouba Seraj returned to Afghanistan from exile in 2003 with the mission to advance women’s rights in the country. In an interview with ABC News Live, she said she made a commitment to Afghanistan to continue to move the country forward and won’t leave the country despite the danger.

During the interview, her words were interrupted by a blast, later determined to be the U.S. military disposing of equipment before exiting the country.

“I cannot leave Afghanistan at this point,” said Seraj. “Everybody worked together to make this country really the way it is. … We all worked very hard, and then it disappeared, and I knew that I have to stick around. I have to stick around to prove it to myself, to prove it to whoever, as far as my young girls.”

Many women in the country fear that the Taliban will revert to the oppressive tactics they used when they ruled in the 1990s, like keeping women at home, out of work and out of schools.

Many also fear that the militant group will retaliate against citizens with connections to America, who’ve worked with the U.S. or Afghan government or who have criticized the Taliban in the past. Under the Taliban’s previous rule, citizens could be stoned to death, have their hands cut off or be publicly executed for violating the Taliban’s laws.

For Arian, the violence Thursday reminded him of the civil war he experienced as a child, when the Soviet Union withdrew from the country and mujahedeen forces turned on each other in 1992.

“Bullets flying, rockets flying and we had to just leave everything, abandon the house,” said Arian. “The schools were destroyed, the hospitals were destroyed, the whole infrastructure was gone.”

Arian believes he’s echoing the voice of the millions of Afghans who’ve lived through the civil war.

“They remember — that’s why they’re physically, mentally tired,” Arian said. “They’re exhausted from running. They’re exhausted from refugee camps, they’re on high alert constantly. And now we see today that there’s nowhere safe for them.”

The future of Afghanistan

For many, the future of Afghanistan and its people hangs in the balance as U.S. troops leave the country behind. While many continue to flock to airports and plan escape routes out of the country, some are hunkering down, determined to rescue the nation they call home.

Arian’s family is divided — his father wants to stay and his siblings want to flee.

“He just told me, ‘Son, I’m tired of running. I’ve spent my entire life running. I just want to die in peace here if there is any peace,'” said Arian. “When I speak to some of my sisters, they’re fearful for their lives. They don’t know whether we would go back again to the civil war that most of them had witnessed along with me, and they have children now.”

Seraj, who has dedicated her life to activism and bettering the conditions of Afghan women for decades, said that all her fears are coming true.

Without plans to leave Kabul, she’s faced with ongoing questions about what’s next for the nation.

“The control is getting out of everybody’s hands,” Seraj said. “We’ve lost a lot of our people. Our soldiers are no longer what they were and keeping us safe. The U.S. Army is no longer there. Nobody’s there. What is going to be happening?”

(KABUL, Afghanistan) — An explosion that killed at least 13 U.S. service members in Afghanistan Thursday was part of a “complex” attack near the Kabul airport, the Pentagon said.

Two ISIS suicide bombers detonated in the vicinity of both the Kabul airport’s Abbey Gate and the adjacent Baron Hotel, according to Gen. Kenneth McKenzie, the commander of U.S. Central Command.

The U.S. service members killed in the explosion near the Abbey Gate included 10 Marines, one Army, one to be determined and one Navy hospital corpsman, or medic, a U.S. official confirmed to ABC News. A 13th service member injured in the attack at Abbey Gate later succumbed to his wounds, a U.S. Central Command spokesperson said Thursday evening.

“We can confirm at this time 10 Marines were killed in the line of duty at Hamid Karzai International Airport. Additionally, several more were wounded and are being cared for at this time,” Maj. Jim Stenger, Marine Corps spokesperson, said in a statement Thursday night.

Another 18 service members were injured in the attack, U.S. Central Command said, up from the 15 initially confirmed by the command.

“We’re still working to calculate the total losses,” McKenzie said during a briefing at the Pentagon Thursday afternoon. “We just don’t know what that is right now.”

The attack marks the third-deadliest single day for American forces in Afghanistan in the 20-year war.

The injured troops are being evacuated from Afghanistan on C-17s equipped with surgical units.

At least 60 Afghan civilians were killed and over 140 others injured in the attack, according to the Associated Press.

The “complex” attack unfolded Thursday evening local time in Kabul, with one explosion at the Abbey Gate causing “a number of US and civilian casualties” and another explosion near the Baron Hotel, a short distance from the gate, Pentagon Press Secretary John Kirby said.

“The attack on the Abbey Gate was followed by a number of ISIS gunmen who opened fire on civilians and military forces,” McKenzie said.

McKenzie said it was his “working assumption” that a suicide bomber was going through the Abbey Gate — being searched and checked by U.S. service members — when the person detonated the vest. The general did not know the size of the bomb or have much information about the explosion near the Baron Hotel. No bomber got onto airport grounds, McKenzie said.

“Clearly there had been a failure” from the Taliban forces checking people outside the airport, the general said.

Hours after the explosions, the militant group ISIS-K, which stands for Islamic State Khorasan Province, claimed credit for the attacks, confirming a suicide bombing.

According to a translation from SITE intelligence group, the Islamic State’s Amaq News Agency issued a report on the attack and provided a photo of the bomber.

The message said the Khorasan Province fighter overcame all security fortifications and reached a distance of “no more than five meters from the American forces.” The fighter detonated his explosive belt, killing 60 and wounding over 100 others, the militant group wrote, citing “military sources,” according to SITE.

McKenzie said the U.S. “will go after” those responsible for the attack “if we can find who’s associated with this,” and that “we believe it is their desire to continue those attacks.”

President Joe Biden reiterated that message during remarks on the attacks Thursday.

“To those who carried out this attack, as well as anyone who wishes America harm, know this: We will not forgive. We will not forget. We will hunt you down and make you pay,” he said.

Prior to the explosions, the U.S. Embassy had warned citizens on Wednesday to leave the airport.

Acting U.S. Ambassador to Afghanistan Ross Wilson, on the ground in Kabul, told ABC’s “Good Morning America” Thursday morning before the explosions that the threat was “clearly regarded as credible, as imminent, as compelling.”

The airport has been the site of tragedy and chaos for days as people rushed to be evacuated since Afghanistan’s government’s collapsed and the Taliban seized control.

Approximately 104,000 people have been evacuated since the effort began on Aug. 14, the White House said Thursday, with a withdrawal deadline set for Aug. 31. The U.S. State Department said Thursday afternoon it believes around 1,000 Americans remain in Afghanistan, a majority of whom want to leave.

Biden said the U.S. “will not be deterred by terrorists” and vowed to pull the remaining Americans and allies out of Afghanistan.

“These ISIS terrorists will not win. We will rescue the Americans in there. We will get our Afghan allies out,” he said Thursday. “And our mission will go on. America will not be intimidated.”

Biden called the service members killed in the attack “heroes who have been engaged in a dangerous, selfless mission to save the lives of others.”

The Pentagon is going through the next-of-kin notification process. Once that is completed, the president will call the troops’ families, White House press secretary Jen Psaki told reporters Thursday.

“We have some sense … what the families of these brave heroes are feeling today. You get this feeling like you’re being sucked into a black hole in the middle of your chest. There’s no way out,” Biden said. “My heart aches for you.”
