The 3 October attack on the Médécins sans Frontières (MSF) hospital in Kunduz killed 10 patients and 12 staff members of the group.
In a statement on Thursday, the medical charity, also known as Doctors Without Borders, said they were informed after Thursday’s “intrusion” that the tank was carrying investigators from a US-Nato-Afghan team which is investigating the attack.
“Their unannounced and forced entry damaged property, destroyed potential evidence and caused stress and fear,” MSF said.
The Pentagon did not immediately respond to a request for comment on the reported intrusion, which came as new evidence emerged that US forces operating in the area at the time of the attack knew that the facility was a hospital.
US special operations analysts were gathering intelligence on the hospital days before the attack, because they believed a Pakistani operative was using it as his base, according to areport by the Associated Press citing an unnamed former intelligence official.
The analysts had mapped the area and drawn a circle around the hospital, the official was quoted as saying. The Pakistani man, described both as a Taliban suspect and as a worker for the Pakistani Inter-Service Intelligence directorate, was killed in the attack, the official told the AP.
