Doctors Without Borders (MSF) says it will review its operations in Afghanistan following the deadly U.S. air strike on a hospital in northern Afghanistan.
The strike hit the MSF-run hospital in the city of Kunduz on October 3, killing at least 22 patients and MSF staff, during fighting between Afghan government troops and Taliban forces.
The charity says 33 people remain unaccounted for.
MSF General Director Christopher Stokes said in Kabul on October 8, "The overwhelmingly shocking nature of the event forces us to take stock of our work in Afghanistan generally and to carefully weigh our commitments to the safety and security of our staff and patients."
"Our future ability to work in Afghanistan will now be based on our ability to obtain a clear reaffirmation of the respect for humanitarian law," he added.
MSF is demanding an international investigation into the bombing.
Three separate investigations -- by the U.S. military, NATO, and the Afghan government -- are already being conducted.
