On 26 August 2021 a suicide bombing at Abbey Gate, Hamid Karzai International Airport, killed 13 US service members and scores of Afghans during the evacuation.

On 26 August 2021 a suicide bombing at Abbey Gate, Hamid Karzai International Airport, killed 13 US service members and scores of Afghans during the evacuation. He did not plant the device.
Context
ISIS-K attacked. Neighbouring 31 August completion is the parent end-state. Neighbouring 29 August drone is a different US instrument. He did not sit as the gate NCO.
31 August withdrawal is neighbouring. The errant drone is 29 August.
The President of the United States signs enrolled bills and is Commander in Chief. He does not write a Senate roll-call, a CBP sector tally, an IDF campaign, or a CBO score. A signature is not unique authorship of every title Congress enrolled. Drafting and floor votes remain with Congress. An archived White House (https://bidenwhitehouse.archives.gov/ (opens in a new tab)) is the official carrier for this term; current whitehouse.gov is not this administration. Office-holding is not authorship of every later CPI print, encounter table, or foreign campaign.
Why it matters
The path is humanitarian access: a completed mass-casualty attack at an evacuation gate is a dated civilian-and-force protection failure on a presidential timetable.

What the sources establish
Special Inspector General for Afghanistan Reconstruction carries the official instrument or communique. Reuters records the same dated act independently.
Established: 26 August 2021 Abbey Gate bombing during the US-run evacuation, independently reported.
Not established: that he uniquely authored the bomber’s act, or a unique later body-count coefficient as a personal tally.
ISIS-K attacked. US forces held the gate. Afghan civilians queued.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies An ISIS-K bombing at Abbey Gate kills US service members and Afghans during the Kabul evacuation, not a later speech about An ISIS-K bombing at Abbey Gate kills US service members and Afghans during the Kabul evacuation.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He owned the withdrawal timetable. ISIS-K attacked. US forces held the gate. Afghan civilians queued. That limit is the alternative to treating office-holding as authorship of every later series.
