Today's demand came a day after President Barack Obama apologized for the October 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 yesterday apologized to the organization and said the US 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."
