Hat tip to Circling the Lion's Den for this report, note the source is the Taliban's website and maybe not a place to visit:http://circlingthelionsden.blogspot....r-died-in.html

An alternative website is:http://jihadology.net/2012/02/13/new...-allah-akhond/

Opening paragraph:
The Taliban yesterday confirmed that its former defence minister....Shaheed Mullah Obaidullah Akhond ... during the Islamic Emirate had died nearly two years ago in a Pakistani prison. Their website says that he was detained on 3 January 2007 by the Pakistani government in Balochistan, but that little was heard from him after that. Only in the last few days did his family receive news from Pakistan that he died in prison in Karachi due to "heart complications" on 5 March 2010.
Closing paragraph:
Was he seen by the Pakistanis as one of the old guard around Mullah Omar, whose outlook did not suit Pakistani interests any longer? Although he was one of those who began to reorganise the Taliban once it had fled into exile in Pakistan, it is possible that he favoured negotiations to end the conflict. He was close to Mullah Barodar, who was also arrested by the Pakistanis, some say because Barodar was also in favour of negotiations with the Karzai regime. If his death was natural why was it covered up by the Pakistanis for so long? Any more information would be appreciated.
This is all very odd IMO. Whose jail? I understand ISI has it's own custody facilities. Why no leaked news? The questions are plenty. Answers few.

Makes one wonder if recent negotiations, which included his release along with others, led to the family being notified. Hardly likely to endear ISI to the Taliban or was he just a casualty of war?
