The American woman who was held captive by a Taliban-affiliated group in Afghanistan and rescued last week by Pakistani troops was rushed to the hospital on Monday for an unspecified reason, her Canadian husband said.

Joshua Boyle told the Associated Press in an email Tuesday that his wife, Caitlan Coleman, "has been through hell, and she has to be my first priority right now."

Coleman, 32, was seven months pregnant when she and her husband, Josh Boyle, were abducted in Afghanistan in 2012 by the Haqqani network. The couple and their three children -- all of whom were born in captivity -- were freed Thursday in a "negotiated release," an official told Fox News.

WHO IS CAITLAN COLEMAN?

Joshua Boyle said after landing at Toronto's airport on Friday that the Taliban-linked Haqqani network killed an infant daughter and raped his wife during the years they were held.

In prior email exchange with AP, Boyle did not respond to a question about the fourth child but later told Canadian Broadcasting Corp. that it was a forced abortion. The Taliban said in a statement it was a miscarriage.

On Monday, Boyle told the AP that he and his wife decided to have children even while held captive because they always planned to have a big family and decided, "Hey, let's make the best of this and at least go home with a larger start on our dream family."

"We're sitting as hostages with a lot of time on our hands," Boyle told AP. "We always wanted as many as possible, and we didn't want to waste time. Cait's in her 30s, the clock is ticking."

Boyle said their three children are now 4, 2 and "somewhere around 6 months."

"Honestly we've always planned to have a family of 5, 10, 12 children ... We're Irish, haha," he wrote in an email.

The parents of Caitlan Coleman have said they are elated she is free, but also angry at their son-in law for taking their daughter to Afghanistan.

"Taking your pregnant wife to a very dangerous place, to me, and the kind of person I am, is unconscionable," Caitlan's father, Jim Coleman said, told ABC News.
