Transcript for American hostage Caitlan Coleman and her family are free after 5 years of captivity

We turn now to the release of an American family by the Taliban. And we've just learned tonight that they are heading back. But not to the U.S. Here's ABC's chief investigative correspondent Brian Ross. Reporter: They were America's littlest hostages, and tonight they and their parents, American caitlan Coleman and Canadian Joshua Boyle, are free after five years of captivity. I am a prisoner of the Taliban. Reporter: Coleman was seven months pregnant when she and her husband were kidnapped while on a hiking vacation in Afghanistan. The Taliban threatened to execute them. They are willing to kill us, willing to kill women, to kill children, to kill whomever. Reporter: Hostage videos over the years showed their plight worsening as she gave birth to three children. My children have seen their mother defiled. Reporter: And the ordeal took its toll on her parents, Lynda and Jim Coleman, in stewartstown, Pennsylvania. I'm not sure I'm ever going to see her again. I'm not sure I'm ever going to see my grandchildren. So it's gotten very, very difficult. Reporter: The Pakistani military launched its top secret mission Wednesday, in a mountainous area near the Afghanistan border, saying it was acting on U.S. Intelligence information. Even before the hostages were in U.S. Hands, president trump made a cryptic reference to the mission. Something happened today where a country that totally disrespected us called with some very, very important news. Reporter: The president has accused Pakistan of giving safe haven to terrorists, but today he thanked them. Right now, a lot of countries are starting to respect the United States of America once again. And Brian Ross with us here tonight. And Brian, you've learned this family is headed back to Canada, not the U.S. Reporter: Yes, David. American officials say the husband refused to board an American military aircraft or to allow U.S. Medical personnel to examine his children. And caitlan Coleman's father tells me tonight they are indeed planning to go to Canada. He says he can't understand why they're doing that, after all the U.S. Did, David, to get them free. All right, Brian Ross tonight. Brian, thank you.
