U.S. authorities knew they were attacking a hospital facility in Afghanistan days before they conducted the operation on Oct. 3, the Associated Press reported on Thursday.
According to the report the special operations analysts were gathering intelligence on the facility because they believed it was being used by a Pakistani operative to coordinate Taliban activity.
U.S. fighter jets struck an Afghan hospital run by Doctors Without Borders, an international charity group based in Geneva, Switzerland.
The attack killed 12 medical staff members and at least 10 patients, three of them children, and injured at least 37 people. At least 33 people are still missing after the airstrikes.
The Pentagon first denied the attack. Then it changed its story to put the blame on Afghan army officials. The U.S. military announced it will make "condolence payments” to the injured and the families of 22 people who lost their lives in the attack and that it will also conduct an investigation into the incident.
