KABUL, Afghanistan (AP) -- Doctors Without Borders says it is pressing its demand for an independent investigation of the tragic U.S. airstrike that hit a hospital run by the medical charity in northern Afghanistan, killing 22 people.
Thursday's demand came a day after President Barack Obama apologized for the Oct. 3 bombing, which also killed 12 medical staff.
Christopher Stokes, the general director of MSF, reiterated the group's call during a press conference in Kabul.
Obama on Wednesday apologized to the organization and said the U.S. would examine military procedures to look for better ways to prevent such incidents.
Stokes says MSF wants the International Humanitarian Fact-Finding Commission "to get the facts of what happened, the truth."
The airstrike took place as Afghan forces fought to retake Kunduz last week from the Taliban.
