Thirteen U.S. troops are among those killed, the Pentagon has confirmed, on what appears to be the worst day for U.S. troops in Afghanistan since 2011
Responding to the attack, US President Joe Biden told those involved: "We will track them down and retaliate."
He also vows to end the rescue operation, but has said that "taking everyone out is not something he can guarantee".
The president says so far there is no evidence of cooperation between the Taliban and the Islamic State, Isis-K, which he claimed was responsible for the attack.

Fear of More Attacks
U.S. commanders are alert for fears of further attacks from ISIS, as well as possible rockets or car bombs targeting Kabul airport, U.S. Army chief Frank McKenzie said.
"We are doing everything we can to be ready," said General McKenzie, as US forces aimed to complete their withdrawal from Afghanistan.
US President Joe Biden has not extended the operation. On Thursday evening, he said that rescue efforts would continue despite the attacks.
