 The documents also said that Christopher Alexander, a top Canadian official working with the United Nations, alleged that Asadullah Khalid had ordered the killing of five United Nations workers by bombing, presumably to protect his narcotics interests.Graeme Smith from The Globe and Mail conducted an investigation on Brigade 888 (a unit under the direct command of Asadullah Khalid) and found that Asadullah Khalid's governor palace contained private detention centres.Graeme Smith further states that the Canadian Generals knew about the brutal technique employed to torture the detainees in those cells.
