Young American mother Caitlin Coleman and her baby are among dwindling number of Taliban-held US hostages

Among the last of the American hostages held by Islamist militants is a woman who used to be one, but is now two.

One-time Pennsylvania rsident Caitlin Coleman, 30, was kidnapped along with her 32-year-old Canadian husband Joshua Boyle in 2012 while the two were travelling through Afghanistan. Coleman was pregnant, and has given birth in captivity.

All eyes have turned to the little family in the wake of the accidental killing of American hostage Warren Weinstein in US drone strike, revealed this week by the White House.

“I would ask that my family and my government do everything that they can to bring my husband, child and I to safety and freedom,” Coleman, wearing a burka, says in the video recording released by their Taliban captors over a year ago.
