美国：多起失误导致错误袭击阿富汗医院

American forces misidentified a target in Kunduz, Afghanistan last month that resulted in a mistaken half-hour aerial attack on a hospital that killed at least 30 people, mostly doctors and patients, according to a U.S. military investigation.

Army Gen. John Campbell, the commander of U.S. and international forces in Afghanistan, said Wednesday that Afghan forces asked for U.S. air support to strike a National Directorate of Security building believed to be occupied by Taliban fighters. According to the report, the AC-130 air crew instead fired 211 shells at a hospital operated by the international charity Doctors Without Borders (MSF) that was 450 meters away.

"This was a tragic mistake," Campbell said in Kabul Wednesday. "This is an example of human and process error. It was directly the result of avoidable human error."

Several factors contributed to the mistake, according to Campbell. The air crew launched more than an hour earlier than planned, missing out on a crucial brief that would normally include identifying no-strike areas such as the MSF hospital. Once in flight, the aircraft's electronic systems malfunctioned, eliminating the crew's ability to transmit video, send and receive email, or send and receive electronic messages.

The crew then believed it was the target of a missile, Campbell told reporters, so they moved out of the aircraft's normal strike range, degrading the accuracy of the targeting system. That loss of accuracy appeared to cause the coordinates of the Taliban target to land on an open field. The crew visually located the "closest, largest" building to that field and, thinking that was the target, fired on it.

Campbell said some military personnel involved in the incident have been suspended from duties pending possible disciplinary action, and that the U.S. intends to assist Doctors Without Borders in rebuilding the hospital.
