Kidnap victim's escape from militant group

Shahbaz Taseer was held hostage in Pakistan's tribal areas for four-and-a-half years until he escaped in March.

Mr Taseer was originally ambushed in Lahore by Uzbek militants. The Uzbek group, together with Mr Taseer, was in turn imprisoned by the Afghan Taliban.

Months before his kidnap, his father, the Pakistani politician Salmaan Taseer, had been shot dead by an Islamic extremist.
