In his chronicle of life as an inmate at Guantanamo Bay, Afghan writer Abdul Rahim Muslim Dost describes his three years of humiliating detention for alleged ties to al-Qaida. Now, he has lost his liberty again - this time believed jailed by the Pakistani intelligence service for the book's fierce criticism of the agency's role in the US-led war on terrorist groups. Just weeks after the Sept. 3 release of "The Broken Shackles of Guantanamo," co-written with his brother and fellow Guantanamo detainee Badruz Zaman Badar, Dost was taken away as he left a mosque after prayers in the northwest Pakistan city of Peshawar, where the family has lived for nearly 30 years. There is no official word on Dost's whereabouts, although the rights group Amnesty International also thinks he is held by the government. Pakistan's military and ISI officials did not respond to requests for comment on Dost's case or the brothers' comments on the agency's conduct.
