( CNN ) -- The Afghan government says armed individuals who may be U.S. special forces carried out acts of torture and murder , allegations that spurred it to demand that members of the elite American military units leave a key province west of Kabul . The U.S. military says it is investigating . NATO 's International Security Assistance Force must stop all special force operations out of Wardak province , an area west of the Afghan capital where the alleged horrors took place , Afghanistan 's National Security Council demanded . And all U.S. special forces must be gone from the province within two weeks . At a meeting of the council , led by President Hamid Karzai , `` it became clear that armed individuals named as U.S. special force stationed in Wardak province engage in harassing , annoying , torturing and even murdering innocent people , '' Karzai 's office said in a statement . It did not indicate who `` named '' the group a U.S. special force . Nine people `` disappeared in an operation by this suspicious force , '' according to the president 's office . And in another incident , a student was taken from his home at night , and his `` tortured body with throat cut was found two days later under a bridge . '' `` Such actions have caused local public resentment and hatred , '' Karzai 's office said . It added that the United States rejects any suggestion that its special forces carried out any such operation . Afghan forces must protect people in the province `` by effectively stopping and bringing to justice any groups that enter peoples ' homes in the name of special force and who engage in annoying , harassing and murdering innocent people , '' the statement said . `` We take all allegations of misconduct seriously and go to great lengths to determine the facts surrounding them , '' U.S. Forces-Afghanistan and the International Security Assistance Force said in a statement . Until military officials speak with Afghan officials about the issue , `` we are not in a position to comment further , '' the statement added . `` This is an important issue that we intend to fully discuss with our Afghan counterparts . '' Last April , the United States and Afghanistan signed a deal giving Afghan authorities an effective veto over controversial special forces missions . The agreement prevents ISAF from conducting such operations without the explicit permission of Afghan officials , said a senior NATO official . And special operations forces will operate under Afghan law , said a statement from Karzai 's office . The complex system fully '' Afghanized '' such operations , putting Afghan commandos in the lead and giving American special forces a `` training and support role , '' a senior Afghan official said . Under the deal , U.S. special forces would be on the ground but would not enter the home of an Afghan unless specifically asked to do so by the Afghan commandos leading the operation , or by other Afghan officials , according to a senior NATO official . This pact followed months of recriminations against special operations raids , particularly at night , that have deeply offended some Afghans angry about foreigners entering their homes . U.S. officials have said such raids are vital to NATO 's operation against insurgents . CNN 's Greg Botelho , Barbara Starr and Nick Paton Walsh contributed to this report .
