Why Is the US So Afraid of Probe Into 'Accidental' Kunduz Hospital Attack?

Not trusting the United States to investigate itself, Doctors Without Borders (MSF) on Wednesday called for the International Humanitarian Fact-Finding Commission to conduct an inquiry into the US airstrike on its hospital in Kunduz.

That same day, US State Department spokesman John Kirby said the United States rejects calls for an independent international investigation. He insisted that the Pentagon remained confident it will conduct a "thorough and transparent inquiry," and does not need any outside body to investigate the attack.
