On Saturday, a hospital in Kunduz that accommodated some 200 people was hit by a series of aerial bombing raids, leaving at least 22 people dead, including 12 staff members of Medecins Sans Frontieres (MSF).
"It’s patently obvious that a war crime was committed [in Kunduz]," Kelly said.
According to Kelly, the United States is ultimately responsible for the hospital bombing, especially given that the Taliban lack the capacity to launch airstrikes.
"If Russia was doing it to another country, you bet it would be regarded as such [war crime]. This is the type of exceptionalism the [US] military wants to claim for us," she said.
There have been numerous incidents of civilian casualties from US airstrikes and night raids in Afghanistan, along with torture allegations that Washington always responds to by saying "it’s under investigation," Kelly added.
On Monday, US Commander of Operation Resolute Support General John Campbell confirmed that Afghan forces called in US airstrikes to eliminate the Taliban threat.
