“Unacceptable.” That’s the reaction from 27-year old Hamdullah to the Pentagon’s announcement Friday that the U.S. military’s deadly airstrike on a Doctors Without Borders hospital in Kunduz, Afghanistan did not amount to a war crime.

His uncle was among the 42 people killed in the October 3, 2015 strike. “This was a deliberate bombardment by the American forces, and we are not satisfied that they have said this was not a war crime,” Hamdullah told Agence France-Presse. Those responsible, he said, “should be publicly put on trial.”
