On 26 August 2021 a suicide attack was carried out by the Islamic State of Iraq and the Levant - Khorasan Province at the Hamid Karzai International Airport, killing more than 170 people, including at least 62 Afghan civilians, 13 US service members, two British nationals and the child of a third British national. Biden made a public address following the attack, in which he honoured the American service members who were killed, calling them "heroes" and saying they lost their lives "in the service of liberty", and stated that the US had evacuated more than 100,000 Americans, Afghans, and others. He expressed deep sorrow for the Afghan victims as well. Biden said to those who wished harm upon the US that "we will hunt you down and make you pay." Biden received increasingly harsh criticism from both Republicans and Democrats in the US Congress, with Republicans calling for his resignation or for his impeachment.
