Recounting a harrowing tale of rape, torture and exploitation, a Pakistani woman who escaped after a year in captivity says she was sold to someone new every few months since being abducted by her husband's friend.

"Every few months I was sold off to someone new and eventually I even began to forget where I was," said the 45-year-old woman, who was kidnapped from Karachi and finally managed to escape in Bhowana tehsil in Punjab province.
