Afghan President Hamid Karzai has assured Canada that a man facing possible execution for converting to Christianity will not be put to death, Canadian Prime Minister Stephen Harper said on Thursday. Harper called Karzai on Wednesday to express his concern over the case of Abdur Rahman, who an Afghan judge said had been jailed for converting from Islam to Christianity and could face death if he refused to become a Muslim again. "He (Karzai) certainly conveyed to me that we don't have to worry about any such eventual outcome. An Afghan judge dealing with the case said on Thursday that the judiciary would not bow to outside pressure over the eventual fate of Rahman, who has not yet been charged.
