A U.S.-Canadian couple freed in Pakistan this week, nearly five years after being abducted in Afghanistan, returned to Canada on Friday where the husband said one of his children had been murdered and his wife had been raped.

American Caitlan Coleman and her Canadian husband, Joshua Boyle, were kidnapped while backpacking in Afghanistan in 2012 by the Taliban-allied Haqqani network. They arrived in Canada with three of their children.

"Obviously, it will be of incredible importance to my family that we are able to build a secure sanctuary for our three surviving children to call a home," Boyle told reporters after arriving at Toronto's Pearson International Airport, wearing a black sweatshirt and sporting a beard.
