An Edmonton man suspected of supporting terrorist groups responsible for killing U.S. troops in Iraq is fighting extradition to the United States. The RCMP arrested Sayfildin Tahir Sharif on Wednesday following a request made by the FBI, and appeared in court Thursday to face extradition. If extradited, Sharif will face “some of the most serious charges an individual can face,” his lawyer, Bob Aloneissi, said. The charges include supporting a terror group and conspiring to kill Americans abroad, and the RCMP are also looking into whether there was any criminal activity committed in Canada. Sharif is accused of aiding a multinational terror group that was responsible for carrying out a 2009 suicide bombing in Mosul, killing five U.S. troops. If convicted, he will most likely be sentenced to life in prison.
