The Army Green Berets that ordered an airstrike on a civilian hospital on Oct. 2 thought the hospital was harboring the Taliban. This is a departure from the Army’s original explanation that it did not know the building was a hospital that the strike was ordered by Afghan forces.

Prior to the airstrike, a senior Green Beret reached out to hospital staff to discuss the possibility that the Taliban were hiding in the building.

Tim Shenk, a spokesman for Doctors Without Borders, told the Associated Press the Army wanted to know “whether our hospital had a large group of Taliban fighters in it. We replied that this was not the case. We also stated that we were very clear with both sides to the conflict about the need to respect medical structures.”

Despite the hospital’s denial that the Taliban were nearby, the Green Berets and Air Force personnel were ordered to “clear the trauma center” of enemies. On Oct. 2, an AC-130 gunship bombed a Doctors Without Borders hospital for an entire hour. The death toll has risen to 30 as more bodies have been extracted from the rubble, including 10 patients, 13 staff members and 7 unknowns.

The Associated Press points out that if the objective were to root out the Taliban, the bombing would have ended the moment the objective was complete. However, the video footage collected on the aircraft during the strike hasn’t been released by the military, so it isn’t possible to know for certain whether the Green Berets were under attack during that time.
