On 25 November 2015, General John F. Campbell, the American commander in Afghanistan, spoke about the results of their internal investigation and described the incident as "the direct result of avoidable human error, compounded by process and equipment failures."[54] Campbell said that the internal investigation had showed that the AC-130 gunship crew misidentified the clinic as a nearby Taliban-controlled government building.[54] The American gunship had identified the building based on a visual description from Afghan troops, and did not consult their no-strike list, which included the coordinates of the hospital as provided by MSF.[54] Electronic equipment malfunctions on the gunship prevented it from accessing email and images, while a navigation error meant its targeting equipment also misidentified the target buildings.[55] The aircraft fired 211 shells at the building in 29 minutes, before American commanders realized the mistake and ordered the attack to stop.[55] The report found that the MSF facility "did not have an internationally-recognized symbol to identify it as a medical facility,".[56] This finding was contested by Joe Goldstein stating that the facility had a MSF symbol on it.[57] According to the report, 12 minutes into the operation, the US military was contacted by MSF, but the faulty electronics on the plane prevented the message from getting through until the attack was over.[55]
