The Pentagon has declassified and publicly released video footage of a US drone strike in Kabul that killed 10 civilians, including seven children, in the final hours of a chaotic American withdrawal that ended a 20-year war in Afghanistan.

The military has said it struck what it thought was an extremist with the Islamic State group’s Afghanistan affiliate who might imminently detonate a bomb near the Kabul airport, where a hurried evacuation was still under way. 

Three days earlier a suicide bombing at the airport had killed 13 US troops and more than 160 Afghans.

When it later acknowledged its error in the August 29 drone strike, Central Command said it determined that the man driving the car had nothing to do with the IS group.
