The US Department of Defense has said that no US troops or officials will face disciplinary action for a drone strike in the Afghan capital Kabul in August that killed 10 Afghan civilians, including seven children.

Pentagon spokesman John Kirby said Secretary of Defense Lloyd Austin had received a high-level review of the strike which made no recommendation of accountability.

"He approved their recommendations," Mr Kirby said. "The secretary is not ... calling for additional accountability measures."

The drone strike on 29 August took place in the final days of the US-led evacuation of Kabul after the Taliban seized control of Afghanistan.

US officials said they had intelligence of a possible attack by so-called Islamic State on the evacuation operations at Kabul airport, and launched a missile from a drone at a target that, in reality, was a family that included an Afghan man who worked for a US aid group.

Deadly drone strike an 'honest mistake' - US military

Last month, an initial report carried out by US Air Force inspector general, Lieutenant General Sami Said, called the strike tragic but "an honest mistake."

The review by Central Command head General Kenneth McKenzie Jnr and Special Operations Command chief General Richard Clarke made use of Lt Gen Said's report and detailed recommendations on procedures for future drone strikes.

But it made no call for anyone to be punished for the mistake.

"What we saw here was a breakdown in process, in execution and procedural events, not the result of negligence, not the result of misconduct, not the result of poor leadership," said Mr Kirby.

If Mr Austin "believed ... that accountability was warranted, he would certainly support those kinds of efforts," Mr Kirby added.

He noted the high level of threat facing US forces following a deadly bombing outside Kabul airport that killed 13 troops - context, he said, was important.

"In this case, in the context of this particular strike ... there was not a strong enough case to be made for personal accountability."

While the Pentagon has said it is working to offer condolence payments and relocation to the family of Afghans killed in the strike, it is still in talks with an aid organisation that employed one of the victims.
