A Canadian special forces soldier was killed and three others wounded in northern Iraq on Friday after Kurdish peshmerga fighters mistook them for ISIS militants, UPI cited the Canadian government as announcing. Canada's Defense Minister Jason Kenney said Sgt. Andrew Joseph Doiron of the Canadian Special Operations Regiment, based at Garrison Petawawa, Ontario, "was killed while conducting advise and assist operations in Iraq when he and other members of the Special Operations Forces were mistakenly engaged by Iraqi Kurdish forces following their return to an observation post behind the front lines." About 600 Canadian troops -- including 69 members of the Canadian Special Operations Forces Command -- are in Iraq as part of Operation Impact.
