KABUL, Muharram 12, 1437, October 25, 2015, SPA -- The number of people killed when U.S. forces bombed a trauma hospital in northern Afghanistan earlier this month has risen to 30, the international medical charity Doctors Without Borders, which ran the clinic, said on Sunday, according to AP. The death toll includes "10 known patients, 13 known staff and seven unrecognizable bodies," the organization said in a statement. The clinic in Kunduz was bombed by U.S. forces on Oct. 3. The charity, also known by its French acronym MSF, said that the corpses were found in the debris of the destroyed hospital buildings and "have not been identified." They may include one staffer and two patients still missing and presumed dead, it said. The bombing happened as Afghan forces with U.S. air support battled to retake Kunduz from Taliban fighters who overran the city on Sept. 28 and held it for three days. Two military inquiries and an Afghan government probe are investigating why the hospital was bombed. The head of U.S. forces in Afghanistan, Gen. John F. Campbell has said the hospital was bombed by mistake after Afghan forces requested an air strike. --SPA 12:38 LOCAL TIME 09:38 GMT www.spa.gov.sa/w
