The Army Green Berets who requested the deadly airstrike on a Doctors Without Borders hospital in northern Afghanistan believed the trauma center to be under Taliban control, the Associated Press reports.
The Pentagon had previously called the raid a mistake. The latest revelations provide more evidence that U.S. troops knew they were bombing a functioning hospital, which if true would be a violation of the international law of war.
In the days before the bombing, "an official in Washington" asked Doctors Without Borders whether the hospital had Taliban fighters inside, which the charity denied, according to a spokeman. The nonprofit said that no gunmen were firing within the hospital compound when the hourlong strike began.
Previous reports said the October 3 attack in Kunduz killed 12 staff member and 10 patients. The latest reports reveal the death toll up to 30. Days after the airstrike, the medical charity said it would withdraw from the Afghan city.
Both the Pentagon and Afghan military are investigating the attack. In a New York Times opinion piece last week, the medical charity called for the United States to participate in an investigation to be led by the International Humanitarian Fact-Finding Commission into the bombing.
