A Canadian who went abroad for terrorist training maintained contact with terrorists in Iran while planning an attack at home, according to a recently released report from the Canadian government.

“The individual had left Canada to participate in … firearms and explosives training at a camp in Afghanistan,” the report said in a section that focused on extremist travelers. “He swore an oath of loyalty to al-Qaida and the Taliban and returned to Canada with the expertise and intent to train, finance and equip a terrorist cell in Ottawa.”
