WASHINGTON (Reuters). The U.S. drone strike that struck Kabul in August killing 10 civilians did not result from criminal negligence. A military inspector general’s investigation found that a number of mistakes, such as not noticing a young child until minutes before it took place.

Ten civilians were killed in the strike of Aug. 29, including seven children. This was an attack that military had previously termed a “tragic error.”

Initial reports by the Pentagon stated that the attack targeted an Islamic State suicide bomber, who was posing an imminent threat for U.S. troops as they complete the final stages of withdrawal from Afghanistan.

This strike was carried out days after an Islamic State suicide attacker had murdered 13 U.S. troopers and scores of civilians from Afghanistan. They had been trying to grab seats on evacuation flights after U.S.-trained Afghan forces collapsed and the Taliban took power in Kabul.

According to the Air Force inspector general, the strikes were caused by errors in execution, incorrect interpretation of information, communication problems, and miscommunications.

It is a terrible mistake. “It’s an honest error,” said Lieutenant General Sami Said (Air Force inspector general).

According to him, evidence was found of a nearby child when he reviewed video footage and data just two minutes before the drone struck.

However, he said that the child was present in his video and that it wasn’t difficult to see at the time.

Said didn’t recommend any disciplinary actions, but stated that it would be up the commanders of what accountability measures should be taken.

Steven Kwon (co-founder and president Nutrition and Education International), who employed one victim, stated that the investigation was “deeply disappointed and inadequate.”

“According to the Inspector General, there was a mistake but no one acted wrongly, and I’m left wondering, how can that be?” Kwon stated in a statement.
