'My father was taken and I don't know why'

Talia's parents separated when she was a little girl, and her father became her only caregiver - from cooking breakfast to making "cool hairstyles" for her for school.

"He was a really nice dad," says Talia, who is 20. "I think my whole life, my worst fear has been losing Papa."

But last November her worst fear came true. Idris Khattak, a well known human rights campaigner, was taken in broad daylight from his car in northern Pakistan, and for seven months Talia had no idea who had taken her father or why.

And then, a breakthrough. In a rare admission of a forced disappearance, Pakistan's military confirmed it had Idris, 56, in custody, and that he was facing charges under the secrets act.

Now the thought of where he might be, and in what condition, keeps Talia up at night. That, and her guilt for the train ride she was on the day he disappeared.
