US President Joe Biden headed to Dover Air Force Base on Sunday to honour members of the US military killed in a suicide bomb attack during the evacuation of civilians from Kabul airport last week.
An Islamic State suicide bombing just outside Kabul airport on Thursday killed scores of Afghans and 13 American troops, reports Reuters.
Biden and his wife, Jill, will meet the families of service members killed in the attack, a White House schedule showed.
They will then witness the transfer of the troops' remains from an aircraft flown to the base in Delaware.
Thursday's attack, which was claimed by ISIS, the Afghan affiliate of Islamic State, was the most lethal incident for US service members in Afghanistan in a decade.
The bombing took place just outside the gates of the airport, where thousands of people have gathered to try to get a flight out since the Taliban returned to power on Aug 15.
The Taliban's rapid advance across the country amid the withdrawal of American and allied troops, and the chaotic scenes at the airport have presented Biden with his biggest foreign policy challenge to date.
Biden has vowed to punish those responsible for the airport bomb. The US military said on Saturday that it had killed two ISIS-K militants in a drone attack in Afghanistan.
